摘要
综述了玻璃态聚合物/渗透剂二元体系、玻璃态聚合物/渗透剂/溶质三元体系的非线性扩散模型。详细阐述了线性和非线性的区别与联系,非线性的形成机制;根据聚合物系统中不同形式的扩散,对之进行了分类,表明非Fick扩散是聚合物系统主要特征之一。
Various kinds of models describing the nonlinear diffusion in glassy polymer/penetrate and glassy polymer/penetrate/solute systems were summarized. The difference and contact between linear and nonlinear were introduced. The mechanisms for the formation of nonlinear were indicated. The dissimilar diffusions in the polymeric systems were expatiated and sorted.
