Preparation and characterization of antibacterial microporous membranes fabricated by poly(AMS-co-DMAEMA) grafted polypropylene via melt-stretching method

Functional polypropylene (PP) is prepared by graft poly(AMS-co-DMAEMA) onto PP chains through melt blending, and then microporous membranes of functional PP are made by casting and stretching, and finally the polycation microporous membranes are obtained via quaternization. The obtained microporous membranes show good hydrophilicity and antibacterial properties.
