Mol. layer deposition (MLD) is a gas-phase deposition technique that can create ultra-thin films with precisely controlled chem. composition and thickness by depositing one monolayer at a time. This makes MLD an attractive technol. for desalination membranes among other applications. Given its relatively recent development, little information has been reported regarding the properties of MLD thin films. We present the results of an initial mech. property study of MLD films with thicknesses ranging from â?0 to 2000 nm. MLD was utilized to create crosslinked polyamide films grown using either m-phenylenediamine (MPD) and trimesoyl chloride (TMC) reactants or piperazine (PIP) and TMC reactants. The elastic modulus of the films was determined using at. force microscopy (AFM). The results show that the modulus was independent of film thickness with values of 4.36 ± 1.19 GPa and 5.24 ± 1.06 GPa for the MLD films grown using the MPD-TMC and PIP-TMC chemistries, resp. These values are of the same order of magnitude as those reported for much thicker polyamide films, but higher than the modulus of polyamide films fabricated using interfacial polymerization In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Product Details of 4422-95-1).
Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Product Details of 4422-95-1
