摘要: |
高分子膜材料的合金化是最为简便有效的膜材料改性方法,不同聚合物之间的相容性是决定高分子合金膜物理性质的关键因素。本文讨论了涉及高分子合金膜体系相容性的几个主要热力学基础问题,包括两组分聚合物相容性的相图分析、高分子共混物在相转化过程中发生相分离的热力学、相分离的临界条件、高分子合金体系相容性的理论预测。 |
Polymer polymer alloy technologies enable two or more polymers to be combined to realize new properties and levels of performance that were not possible with the individual polymers themselves. Therefore, they have become the most feasible and effective methods to realize the modification of polymeric membrane materials. The miscibility and compatibility of the various polymeric components, and thus the formation of homogenious phase to multiphase systems in casting solution play a decisive role in influencing the physical properties of the membranes prepared from it. In this article, the principles of thermodynamic to evaluate the miscibility and compatibility between polymers in polymer blend or alloy systems were thoroughly reviewed and discussed, including the basic theory and models for polymer miscibility study, the analysis of the ternary phase diagram of polymer A-polymer B-solvent mixture system, the thermodynamics of polymer blend phase separation during phase inversion, the critical phase separation condition, and the theoretical prediction of the polymer blend miscibility and compatibility. |
