Advanced functional polymer membranes

Polymer surface with graft chains

Recently a variety of technologies have been proposed for improving surface properties of polymers. Among them is surface grafting of polymers. Although this is a rather new technology, polymer surface grafting offers versatile means for providing existing polymers with new functionalities such as hydrophilicity, adhesion, biocompatibility, conductivity, anti-fogging, anti-fouling, and lubrication. This review article describes various methods of grafting and grafted surface characterizations. Medical and non-medical applications connected with this polymer surface grafting are also presented referring to recent publications.

Surface modification of polymers by grafting

Argon plasma-pretreated polytetrafluoroethylene (PTFE) films were subjected to further surface modification by near-UV light-induced graft copolymerization with acrylic acid (AAc), sodium salt of styrenesulfonic acid (NaSS), and N,N-dimethylacrylamide (DMAA). The surface compositions and microstructures of the modified films were characterized by angle-resolved X-ray photoelectron spectroscopy (XPS). A stratified surface microstructure with a significantly higher substrate-to-graft chain ratio in the top surface layer than in the subsurface layer was always obtained for PTFE surface with a substantial amount of the hydrophilic graft. The stratified surface microstructure was consistent with the observed hysteresis in advancing and receding water contact angles. The graft yield increased with Ar plasma pretreatment time and monomer concentration. Covalent immobilization of trypsin on the AAc polymer-grafted PTFE films was facilitated by water-soluble carbodiimide (WSC). The effective enzyme activities incr...
