Composite materials prepared by phase inversion deposition of polyacrylonitrile onto porous polyethylene films

Composite ultrafiltration membanes were prepared by deposition of polyacrylonitrile onto a porous polyethylene support by the phase inversion procedure. The supports were hydrophilized by treatment in a barrier discharge argon plasma. Methods were suggested for controlling the pore size in the polyacrylonitrile layer. The filtration characteristics of the membranes and their mechanical properties were determined.
