Abstract There is an increasing interest in synthetic polymeric materials with surface and permeation properties triggered by environmental stimuli such as temperature, pH, photo field. The present review is concerned with the recent progress in the field of such microporous membranes. The fabrication, stimuli-sensitivity and the mechanism(or model) of environmental-sensitive porous membranes are summarized.

摘要 对微孔膜材料进行表面改性后可得到具有环境响应性的“化学阀”，其渗透、分离性能可随外界环境的变化而相应改变。本文较详细地介绍了这类功能膜的制备方法，重点描述了在不同pH值、温度、光等的作用下膜的刺激响应功能及其模型解释。
