Composite PSF-PANI membranes for proteins recovery

This work reports the performances of the polysulfone-polyaniline (PSf-PANI) porous composite membranes for proteins recovery. Polysulfone-polyaniline porous composite membranes are obtained by phase inversion with chemical reaction. PANI is obtained in-situ by oxidative aniline polymerization. Composite membranes are morphological studied by electron microscopy and characterized by water solutions permeation at different pH and pressures. Polysulfone-polyaniline porous composite membranes UF processes performances to BSA separation are also reported.
