摘要
采用表面改性的方法(强碱处理)制备具有温度敏感聚偏氟乙烯(PVDF)中空纤维智能膜,并对其环境响应性进行了研究。结果表明,对于温度敏感膜可以分别通过控制温度的变化,有效的控制纯水通量和卵清蛋白的截留率。
Temperature sensitive poly(vinylidene fluoride)(PVDF) hollow-fiber membranes were prepared by grafting polymerizing N-isopropylacrylamide onto inert porous membranes utilizing chemically treating the porous membrane in a strong alkali solution. The effect of environmental conditions on the membrane was evaluated. The fluxes of water and egg protein across a temperature sensitive PVDF-g-NIPA was effectively controlled by temperature and concentration of cross-linking agent.
