PTFE/polyamide thin-film composite membranes using PTFE films modified with ethylene diamine polymer and interfacial polymerization: Preparation and pervaporation application

Poly(tetrafluoroethyelen)/polyamide (PTFE/PA) thin firm composite membranes are prepared using ethylene diamine polymer modified films as substrates through interfacial polymerization and applied for pervaporation dehydration.
