Bioinert Fibrous Polypropylene Membranes via In Situ Polymerization of Zwitterionic Poly(sulfobetaine methacrylate).

ABSTRACT: This study reports the fabrication of a biocompatible polypropylene (PP) fibrous membrane via an in situ polymerization process, generating a dual network of PP fibers and poly(sulfobetaine methacrylate) (poly(SBMA)). In this method, the synthesis of the polymer and the modification process happen in a single step. Notably, the modification was achieved without the incorporation of hydrophobic groups in the modifying polymer, demonstrating that the physical entanglement of poly(SBMA) and PP was sufficient to produce a stable biocompatible membrane. The presence of the poly(SBMA) coating was confirmed through various characterization techniques. A reduction in the water contact angle indicated increased hydrophilicity, while Fourier-transform infrared spectroscopy and X-ray photoelectron sp
