ATRP法在真丝表面接枝HEMA的研究
Study on the grafting of HEMA on silk surface via ATRP method
摘要
Abstract
Hydroxyethyl methacrylate (HEMA) was grafted onto silk surface using 2-bromoisobutyryl bromide (BriB-Br) modified silk as macroinitiator, and CuBr/N,N,N',N",N"-pentamethyldiethylenetriamine (PMDETA) as catalyst system, in aqueous medium via atom transfer radical polymerization (ATRP) method.The effects of monomer concentration, catalyst concentration, pH value and reaction time on silk grafting were studied.The grafted silk was characterized by ATR-FTIR, X-ray diffraction and scanning electron microscope (SEM),and its physical properties were tested.The results showed that HEMA was successfully grafted onto silk surface via ATRP method; the grafting primarily happened at the amorphous region of silk fibroin and the grafted polymers uniformly distributed on the silk surface.The crease resistance of the grafted silk fabric was remarkably improved.关键词
