摘要
采用强碱处理方法制备具有温度、pH双敏感的聚偏氟乙烯(PVDF)中空纤维智能凝胶膜,并对智能水凝胶及其智能膜的环境响应性进行了研究。结果表明,这种双敏感智能凝胶膜可以分别通过控制温度和pH值的变化,有效地控制纯水通量和卵清蛋白的截留率。
The temperature and pH sensitive PVDF hollow fiber hydrogel membrane was prepared by using a novel approach, alkaline treatment method. The temperature and pH sensitive behavior were investigated by the flux of pure water and the rejection of ovalbumin. The results show that the flux of pure water and the rejection of ovalbumin are controlled effectively through adjusting temperatures and pH.
