摘要
荷电膜以其特殊的分离机理,使之与电中性膜相比在分离性能、通量及膜的使用寿命等方面具有不可比拟的优势。大多数的荷电膜是经过一系列物理化学改性制得的,荷电膜材料的研究为新型膜材料的开发拓宽了领域,随着对膜性能要求的日益提高,荷电膜的研究具有重要的意义。本文首先介绍了荷电膜所用到的材料及其用途,并对所用到的材料进行分类,然后重点论述了荷电膜的制备及其表征方法(膜电位的测试方法),最后指出荷电膜需要进一步深入研究的内容。
Compared to uncharged membrane, charged membrane with a special separation mechanism, has many unparalleled advantages in separation property, flux and usage time. Most of the charged membranes is obtained through a series of physical and chemical modification, charged membrane materials broaden the field of new types of membrane materials. With higher performance requirements of the membrane increasing, the research on charged membrane has important significance.
In this paper, firstly the materials used by the charged membrane and its application fields were introduced, and the charged membrane materials were classified, then focused on the charged membrane preparation and characterization（membrane potential testing methods）, finally some problems deserving further research in this field were presented, too.
