The separation performance of polyamide (PA) thin film composite (TFC) membrane is critically influenced by the substrates. Numerical models and exptl. studies suggest that substrates with high porosity comprising small pores can effectively improve membrane performance. Here we report that a com. polyethylene (PE) micro-porous membrane with high porosity was chosen as substrate for fabricating PA TFC membrane. The PE substrate was modified by co-depositing the copolymers of gallic acid and γ-aminopropyltriethoxysilane to improve its bulk hydrophilicity. The porosity, pore size, morphol. and chem. properties of the modified PE substrates were characterized. The resultant PA TFC-PE membrane had a favorable water permeance of 2.33 ± 0.06 L m-2 h-1 bar-1 as well as a high NaCl rejection of 99.0 ± 0.4% because of the suitable porosity, pore size and hydrophilicity for interfacial polymerization reaction. Our work is expected to provide an efficient way for the modification of hydrophobic porous membrane for fabricating PA TFC membrane. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1SDS of cas: 4422-95-1).
Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).SDS of cas: 4422-95-1
