Abstract

Films obtained from aqueous solutions of chitosan succinamide sodium salt are studied. It is found that the process of water vapor sorption by polymer films proceeds in an anomalous mode and the diffusion coefficients of water and the dioxidine drug in the films depend on the thickness of the samples and the concentration of the polymer in the initial solution. It is assumed that the dependence of the diffusion coefficients on the film preparation conditions is determined by the difference in the supramolecular organization of the films formed under different conditions, as well as by the difference in the surface roughness of the films.

超分子组织对水溶液制备的壳聚糖琥珀酰胺薄膜某些特性的影响

摘要

研究了从壳聚糖琥珀酰胺钠盐水溶液获得的薄膜。发现聚合物膜对水蒸气的吸附过程以反常方式进行，并且膜中水和双氧还氧药物的扩散系数取决于样品的厚度和初始溶液中聚合物的浓度。假设扩散系数对膜制备条件的依赖性是由在不同条件下形成的膜的超分子组织的差异以及膜的表面粗糙度的差异所决定的。
