The influence of membrane formation on functional performance of organic solvent nanofiltration membranes

摘要

Organic solvent nanofiltration (OSN) has been used in recent years on many new applica-tions [1].Usually OSN membranes are made from polydimethylsiloxane (PDMS) and poly-imides (PI).PIs have shown to have good chem-ical stability (low swelling in organic solvents).In particular,Lenzing P84 (P84) shows better chemical resistance than other PIs such as Mat-rimid and Sixef [2],making it a prime candidate for use in OSN.
