摘要
通过气体在玻璃态高分子膜中的吸收过程分析,认为在膜中气体分子与膜之间的相互作用将影响吸收等温线。假设气体在膜中的溶解过程类似于在溶液中的溶解过程,推导得出了普遍化双方式吸收模型。该模型中考虑了气体吸收浓度对气体在玻璃态膜中吸收过程的影响,几乎能够描述各种吸收过程。
Through the analysis of sorption of gas in glassy polymer, it is considered that the interaction between gaseous molecule with its membrane will affect the sorption isotherms. A generalized dual-mode model is obtained by considering that the ordinary dissolution of gas in membrane is similar to that in liquid solution. The influence of gaseous sorption concentration on the sorption of gas in glassy polymer is considered in this model. The model can be used to describe almost all kinds of sorption of gases in polymers.
