And the article contained the following:

The polyethersulfone (PES)-based composite polymers have been extensively studied for many years as the core of various scientific activities, such as fuel cell production, water treatment, reverse osmosis, ultrafiltration, nanofiltration, and gas separation, which represent a significant field of research for several applications. In the present study, PES and polyvinylpyrrolidone-coated magnetic core-shell nanoparticles (NPs) are synthesized. Following this, a range of these NPs and PES blend polymers are prepared Then, analyzing methods are used for identification and characterization of a variety of these samples. Since some properties of the samples have been improved, and others are attenuated, the best composition could not be selected from the samples without a logical process. To do so, a multiple-criteria decision-making (MCDM) technique that considers all the desired parameters is utilized. A MCDM algorithm is applied to create a ranking of alternative properties from the best to the worst, alongside math. calculations which accounts for the relative importance of the criteria. Results have shown that PES film with 15% of polymer-coated NPs presents the best performance based on the desired properties. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Product Details of 80-07-9

On August 1, 2020, Jin, Pengrui; Yuan, Shushan; Zhang, Gang; Zhu, Junyong; Zheng, Junfeng; Luis, Patricia; Van der Bruggen, Bart published an article.Recommanded Product: 4,4′-Sulfonylbis(chlorobenzene) The title of the article was Polyarylene thioether sulfone/sulfonated sulfone nanofiltration membrane with enhancement of rejection and permeability via molecular design. And the article contained the following:

Further improvement of nanofiltration is significantly hindered by the trade-off between the permeability and selectivity. This study proposes a new strategy of significantly improving performance by enhancing the effective membrane area, hydrophilicity, membrane porosity, neg. charges of a membrane, and decreasing pore size through designing a new polyarylene thioether sulfone/sulfonated sulfone (PATS/SS) copolymer. Via copolymerization, thioether (-S-) and sulfonic groups were integrated in one polymer, endowing it with oxidizable properties, in combination with improved hydrophilicity, neg. charges and membrane porosity. Nanofiltration membranes prepared from this copolymer are hydrophilic (contact angle: 69.1°) and neg. charged. After the -S- groups were altered to sulfone (-SO2-) units by a simple oxidization treatment, both hydrophilicity (contact angle: 37.9°) and surface charge were enhanced, rendering improved antifouling properties. Furthermore, the solvent stability of oxidized membranes was significantly improved, maintaining the structure intact even in N-methyl-2-pyrrolidone (NMP) for 24 h. Most importantly, a simultaneous enhancement of rejection (by 85.2%) and permeability (by 105%) of the membrane was observed when applied in nanofiltration for water purification and dye desalination, significantly improving performance compared to currently reported membranes. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Recommanded Product: 4,4′-Sulfonylbis(chlorobenzene)

On May 13, 2022, Corrado, Tanner; Wang, Tao; Huang, Zihan; Aboki, Joseph; Ford, Hunter O.; Schaefer, Jennifer L.; Guo, Ruilan published an article.Category: chlorides-buliding-blocks The title of the article was Polymer Morphological Effect on Gas Transport within Triptycene-Based Polysulfones. And the article contained the following:

In this study, the effect of polymer morphol. on chain packing and phys. and gas transport properties was explored via the creation and study of three polysulfone copolymer membranes-a random copolymer, 15k-15k (g/mol) multiblock copolymer, and polymer phys. blend-each containing a 50:50 mol equiv of triptycene and phenolphthalein bridging units. These polysulfones with varied morphologies were directly compared to each other, as well as to their relevant triptycene- and phenolphthalein-based polysulfone homopolymer counterparts. Each polysulfone containing equivalent amounts of triptycene and phenolphthalein exhibited similar phys. properties, densities, and fractional free volume results regardless of combination method. Similarly, gas permeation data followed an expected trend of performance between that of the two homopolymers for H2/CH4 and O2/N2 separations Uniquely, the random copolymer exhibited unexpected suppression of methane permeability and, to a lesser extent, nitrogen permeability, leading to the highest selectivities for CO2/CH4 and CO2/N2 among the series. This can likely be attributed to the greater abundance of triptycene and phenolphthalein units in close proximity along the polymer backbone in the random copolymer, leading to synergistic performance effects from different inter- and intrachain interactions unattainable in the multiblock, phys. blend, and homopolymers.

Gruenig, Lara; Handge, Ulrich A.; Koll, Joachim; Gronwald, Oliver; Weber, Martin; Hankiewicz, Birgit; Scharnagl, Nico; Abetz, Volker published an article in 2020, the title of the article was Hydrophilic dual layer hollow fiber membranes for ultrafiltration.SDS of cas: 80-07-9 And the article contains the following content:

In this study, a triblock copolymer was used as additive to fabricate new dual layer hollow fiber membranes with a hydrophilic active inner surface in order to improve their fouling resistance. The polymeric components of the solutions for membrane fabrication were poly(ether sulfone), poly(N-vinyl pyrrolidone), and the triblock copolymer. The additive consists of three blocks: a middle hydrophobic poly(ether sulfone) block and two outer hydrophilic alkyl poly(ethylene glycol) blocks. By varying the additive concentration in the solutions, it was possible to fabricate dual layer hollow fiber membranes that are characterized by a hydrophilic inner layer, a pure water permeance of over 1800 L/(m2 bar h) and a mol. weight cut-off of 100 kDa similar to com. membranes. Contact angle and composition determination by XPS measurements revealed the hydrophilic character of the membranes, which improved with increasing additive concentration Rheol., dynamic light scattering, transmission, and cloud point experiments elucidated the mol. interaction, precipitation, and spinning behavior of the solutions The low-mol. weight additive reduces the solution viscosity and thus the average relaxation time. Furthermore, phase separation occurred at a lower non-solvent concentration and the precipitation time increased with increasing additive content. The chosen process parameters as well as the additive solutions provide an easy and inexpensive way to create an antifouling protection layer in situ with established recipes of poly(ether sulfone) hollow fiber membranes.

And the article contained the following:

Nanochannels fabricated from the aggregation of charged amphiphilic nanoparticles are of growing interest. The nanochannel size can be further affected by electrostatic interactions between these nanoparticles and metal cations. Herein, size-tunable nanochannels (from 0.5 to 1.4 nm in average) are obtained via regulating the aggregation of anionic nanoparticles using sulfonated polysulfone (SPSF) nanoparticles as a model. Transmission electron microscope (TEM) images and dynamic light scattering (DLS) curves show the aggregates of SPSF nanoparticles in a wide range from nanoscale to micrometer-scale via adding different metal cations. Further anal. of the nanochannels shows the quant. correlation between ionic strength of metal cations (ISMC) and nanochannel size. Preliminary evaluation of the size-tunable nanochannels exhibits a good separation performance with the Na2SO4 rejection of 98.3% and water flux of 5.8 L m-2 h-1 bar-1, indicating a high level among the reported researches.

On March 25, 2020, Corrado, Tanner; Huang, Zihan; Aboki, Joseph; Guo, Ruilan published an article.Synthetic Route of 80-07-9 The title of the article was Microporous Polysulfones with Enhanced Separation Performance via Integration of the Triptycene Moiety. And the article contained the following:

Here, we report the synthesis of two polysulfones containing either triptycene or phenolphthalein as the bulky bridging unit in the polymer backbone to investigate the influence of the rigid, unwieldy structures on chain rigidity, fractional free volume, and gas transport properties. Incorporation of the triptycene unit provided the most rigid backbone, greatest fractional free volume, and strongest gas separation performance, because of its exceptional combinations of permeability and selectivity, relative to many com. polymers and other polysulfones reported in the literature. In addition, integration of the triptycene unit and its intrinsic, configuration-based free volume provided good resistance to phys. aging. In particular, the triptycene-based polysulfone experienced exceptional H2/CH4 selectivity (156) combined with nearly doubled H2 permeability, as well as promising O2/N2 separation performance with an O2 permeability of 1.5 Barrer, which is an ∼21% increase, relative to that of the bisphenol A-based com. polysulfone, to go along with an O2/N2 selectivity of 7.7.

On May 5, 2022, Ramos-Rivera, Gilberto; Suleiman, David published an article.Related Products of 80-07-9 The title of the article was High-performance blended membranes based on poly(arylene ether sulfone) and sulfonated poly(styrene-isobutylene-styrene) for direct methanol fuel cell applications. And the article contained the following:

In this study, two series of poly(arylene ether sulfone)s (PAES) with hydrophobic blocks made of 4,4′-dihydroxyphenyl (BP) and 2,2-bis(4-hydroxyphenyl) propane (BPA) were synthesized. The copolymers were prepared by a coupling reaction between decafluorobiphenyl (DFBP) end-capped nonsulfonated block (PAES A or B) and sulfonated block (SPAES B). The reactive behavior of DFBP facilitates the low-temperature coupling reaction (below 105°C). The final copolymers were blended at distinct weight percent ratios (0, 20, 30, and 40) with poly(styrene-b-isobutylene-b-styrene) (SIBS) at a sulfonation level of 88% to obtain strong and flexible membranes. Morphol., thermal stability, and conduction properties of the resulting membranes were measured and reported here. Results suggest that phase segregation between hydrophobic and hydrophilic domains occurs below 1 meq. g-1 ion exchange capacity. These membranes have low water absorption and high thermal stability. Incorporating SIBS 88 into the blend added elastomeric behavior enhancing transport properties and addnl. ionic domains, achieving proton conductivities of 0.21 S cm-1 for BPA-based membranes at 50°C (40% SIBS 88). The selectivity of the studied membranes surpasses Nafion 117, making them strong candidates for proton exchange membranes in direct methanol fuel cell applications. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Related Products of 80-07-9

On July 15, 2021, Chang, Kevin; Luo, Hongxi; Bannon, Sean M.; Lin, Sin Yan; Agata, Wendy-Angela Saringi; Geise, Geoffrey M. published an article.Application In Synthesis of 4,4′-Sulfonylbis(chlorobenzene) The title of the article was Methoxy groups increase water and decrease salt permeability properties of sulfonated polysulfone desalination membranes. And the article contained the following:

A promising desalination membrane material, sulfonated polysulfone, was structurally modified to increase its water/salt transport selectivity. The structural modification was achieved by adding methoxy groups to the polymer backbone. This modification simultaneously increased water permeability and decreased salt permeability. These changes in properties are both favorable for desalination applications, and they may result from changes in polymer d. and the free volume element size distribution. Relative permittivity and salt sorption data for these charged polysulfones suggest that Donnan exclusion may influence salt sorption properties to a greater extent than electrostatic or dielec. exclusion forces, which is reasonable for charged polymers. The Donnan-Manning model did not quant. describe the salt sorption properties of the sulfonated polysulfone materials perhaps due to a combination of low water content and a heterogeneous distribution of fixed charge groups throughout the polymer. Interestingly, addition of methoxy groups to the charged polysulfone backbone more strongly influenced the diffusion properties than the sorption properties, and this observation may be important to guide the engineering of highly selective polymeric materials for desalination applications. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Application In Synthesis of 4,4′-Sulfonylbis(chlorobenzene)
