摘要

提出了聚电解质层层自组装线性多层膜的电荷分区互补理论

基于该理论建立了表面电荷密度、诱导电荷、聚电解质的吸附量和形态、膜内电荷存在形态之间的半经验数学模型。提出了计算膜内聚苯乙烯磺酸钠(PSSS)与聚烯丙基胺盐酸盐(PAH)的离子化率和电荷诱导效应的方法

讨论了处于最外层和次外层聚电解质的离子化率的不同及其与聚电解质强弱的关系。该方法比红外光谱法和光电子能谱法更简便

可用于研究所有聚电解质的离子化率。

Abstract

A charge partition complementary theory of polyelectrolyte multilayer films having the linear growth via layer-by-layer self-assembly was put forward. The theory are used to study a semi-empirical mathematical model about the relation between charge overcompensation

induced charge

polyelectrolyte adsorption amount and conformation

forms of intra-film charge and charge density. The ionization rate of polyelectrolyte inside multilayer film and the induced charge can be calculated deriving this model. The ionization rates of the outer layer and the outermost polyallylamine hydrochloride were discussed. The method is simpler and more convenient than the infrared spectrometry method and photoelectron spectroscopy method. The ionization rates of all polyelectrolytes can be researched using the method.
