以氯化亚铜(CuCl)/2,2’-联吡啶(BPy)为催化配位体系,N,N-二甲基乙酰胺(DMAc)作为溶剂,通过原子转移自由基聚合(ATRP)法在聚氯乙烯(PVC)分子链上接枝烯丙基聚乙二醇(APEG).X射线光电子能谱(XPS)、红外光谱(FT-IR)和核磁共振(1H-NMR)表明:APEG单体成功地接枝到了PVC链上;改性材料经相分离法制备过滤膜,膜的孔径分布范围为0.117 μm～0.247μm,接触角在300 s内由81°下降至64.4°;0.05 MPa跨膜压差下,初始纯水通量为1677 L/(m2·h);牛血清蛋白(BSA)液过滤试验共循环3次,0.05 MPa跨膜压差下,首次循环初始通量为737 L/(m2·h),经3次循环后BSA通量稳定在101 L/(m2·h),显示出较好的抗污染性能.
