本文研究了聚甲基丙烯酸和几种主链型聚联吡啶间通过离子相互作用形成聚离子复合物的过程以及复合物的结构。实验表明,聚离子复合物的形成和结构受聚阳离子电荷密度、构象、疏水性、分子量、聚阴离子的离解度、溶液的离子强度,甚至时间等诸多因素的制约;复合物的形成过程主要可分成三步:初级复合物的形成、复合物链构象的调整过程,复合物链之间的聚集过程。 In this paper, poly (methacrylic acid) and several main chain polypyridines were studied to form polyion complexes through ionic interactions and the structure of the complexes. The experimental results show that the formation and structure of polycation complexes are controlled by many factors such as charge density, conformation, hydrophobicity, molecular weight, dissociation degree of polyanion, ionic strength of solution and even time. Divided into three steps: the formation of primary complexes, complex chain conformation of the adjustment process, the aggregation between the chains of the process.
