Polypropylene non-woven fabric membrane via surface modification with biomimetic phosphorylcholine in Ce(IV)/HNO3 redox system
关键字：2-Methacryloyloxyethyl phosphorylcholine, Hemocompatibility, Graft copolymerization, Polypropylene non-woven fabric (NWF) membrane, Redox graft polymerization
Surfacemodification of polypropylene non-woven fabric membrane (NWF) for improving its hemocompatibility was developed by grafting a biomimic monomer, 2-methacryloyloxyethyl phosphorycholine (MPC). The NWF membrane surface was first activated by potassium peroxydisulfate to form hydroxyl groups, and then grafted with MPC using ceric (IV) ammonium nitrate as the redox initiator. Th...

Surface modification of poly(styrene-b-(ethylene-co-butylene)-b-styrene) elastomer via photo-initiated graft polymerization of poly (ethylene glycol)
关键字：Poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) copolymer, Photo-initiated graft polymerization, Poly(ethylene glycol) methyl ether methacrylate (PEGMA), Wettability, Hemocompatibility
Poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) copolymer biomedical elastomer was covalently grafted with poly(ethylene glycol) methyl ether methacrylate (PEGMA) via a photo-initiated graft polymerization technique. The surface graft polymerization of SEBS with PEGMA was verified by ATR–FTIR and XPS. Effect of graft polymerization parameters, i.e., monomer concentration, U...

Antibacterial and hemocompatibility switchable polypropylene nonwoven fabric membrane surface
关键字：antibacterial, UV-induced graft polymerization, polypropylene nonwoven fabric membrane, hemocompatibility, zwitterionic polymer
In this article, a facile approach to fabricate a biofunctional polypropylene nonwoven fabric membrane (PP NWF) with a switchable surface from antibacterial property to hemocompatibility is presented. In the first step, a cationic carboxybetaine ester monomer, [(2-(methacryboxy) ethyl)]-N,N-dimethylamino-ethylammonium bromide, methyl ester (CABA-1-ester) was synthesized....
