摘　　要：近十年来,人们开始关注开发对外界环境条件变化具有敏感反应与自我调节的功能膜。在检测、分离、纯化、药物释放和传感器等领域迫切需要一种对某种特定物质的渗透通量或截留效果可随pH的改变而发生变化的膜。文章主要介绍了环境敏感膜(EMR)的研究现状、pH敏感膜的研究进展以及高聚物的辐射接枝方法和原理,总结了辐射接枝的特色与创新之处。Since the last decade, people have paid more attention to development of functionat membranes which hade a sensitive reaction and can adjust itself to the change of environment. In the field of examination, separation, purification, medication release and sense organ, a kind of membrane through which the penetrate flux and cutting effect can change with pH value was needed. So in the paper we mainly introduced the research situation of environment sensitive membrane （EMR） present, the research development of pH-sensitive membrane, the method and the principle of high polymer radiation stem grafting, summarized the characteristic and the innovation place of radiation stem grafting.
