敏感性高分子功能膜的研究进展

Advance in Study of Functional Membranes of Sensitive Polymers

某些高分子凝胶膜、膜表面或微孔内接枝改性膜、液晶膜具有化学阀的功能 ,其膜的通透性随外界环境条件变化而改变。详细介绍了 pH、温度、电场等外界环境条件变化对此三类膜的敏感性及通透性的影响 ,以及敏感性功能膜在物质的分析与检测。

Chemical valve is one of the ‘chemomechanicalsystem’, which means that it is sensitive to changes in the environment, such as pH, ionic strength, ion species, temperature, function groups, etc. These kind of environment-sensitive membranes can be used in various areas, such as separation and controlled drug delivery system. In this paper, the development of its research, preparation method, characteristics of the chemical valve are introduced, as well as the prospective applications are foreseen.
