等离子体引发的RAFT接枝聚合对聚丙烯多孔膜的表面改性
Surface modification of porous polypropylene membrane by plasma-initiated RAFT graft polymerization
摘要
Abstract
A reversible addition-fragment chain transfer (RAFT) graft polymerization method, initiated by the pulsed plasma, was used to modify the surface of porous polypropylene ( PP) membrane, with 2-cyanoprop-2-yl dithiobenzoate (CPDB) used as the RAFT agent and acrylic acid as the monomer. The result of the graft polymerization kinetics was in agreement with that of the RAFT polymerization, and the plasma-initiated method was feasible. The surface chemistry, the surface morphology and the porous structure of modified PP membranes were evaluated by Fourier transform minfrared spectroscopy ( FT-IR) , scanning electron microscope (SEM) ,mercury intrusion, and water flux measurements. Graft amounts of modified membranes exhibited a linear increase with the increase of the conversion, while pore sizes and water fluxes were decreased continuously with the prolonging of polymerization time. The pore size of the porous PP membrane was regulated by a simple tune of the polymerization time or the monomer conversion by the RAFT graft polymerization.关键词
