用自组装法制备聚合物纳米复合膜

文章比较了自组装法（ｓｅｌｆ－ａｓｓｅｍｂｌｙ，ＳＡ）与Ｌａｎｇｍｕｉｒ－Ｂｌｏｄｇｅｔｔ技术（ＬＢ）及其它方法在制备聚合物纳米复合膜时的优劣。ＳＡ法由于操作简单、膜的结构稳定性较高，因此较ＬＢ技术等具有更大的实用价值。利用ＳＡ法，可以制备各种有机聚电解质与其带相反电荷的有机聚电解质、粘土化合物及无机纳米颗粒等组成的聚合纳米复合膜。

Ultrathin Polymeric Nanocomposite Films Prepared by Self assembly

Self assembly(SA),a new method of creating ultrathin polymeric nanocomposite films is introduced in this paper,which is based on the electrostatic attraction between opposite charges.In contrast to classic Langmuir Blodgett and other techniques,films' good long term thermal and mechanical stability,relative ease of preparation and high degree of versatility render SA technique amenable to a large variety of diverse polyelectorlyte systems,such as polyelectrolyte polyelectrolyte,polyelectrolyte clay platelets,polyelectrolyte protein,polyelectrolyte inorganic nanaparticles,and so on.
