Biocompatibility of polypropylene non-woven fabric membrane via UV-induced graft polymerization of 2-acrylamido-2-methylpropane sulfonic acid

► The grafting of sulfonic-based polymer (poly(AMPS)) on polypropylene non-woven fabric (NWF PP) membrane surface. ► Surface grafting on NWF PP membrane via O2 plasma pretreatment combining with UV-irradiated technique. ► Obviously enhanced resistance to static protein adsorption and platelet adhesion was acquired by the modified NWF PP membrane.
