剪切对聚合物共混体系相行为影响理论研究的进展

PROGRESS IN THE THEORIES OF POLYMER BLENDS′ PHASE BEHAVIOR UNDER SHEAR FLOW FIELD

从热力学理论和热力学模型两个方面综述了剪切对聚合物共混体系相行为的影响。剪切对聚合物共混体系相行为影响的理论研究中,出现了众多的热力学理论模型,包括Wolf理论模型、Onuki理论模型、Lyngaae-Jorgensen理论模型以及焓熵竞争模型等。文中较为详细地阐述了各种模型的内容、条件以及优缺点,并着重介绍了现在最为流行的Wolf热力学模型在剪切对二元和三元聚合物共混体系的理论研究中的具体应用。

The theories and the models of the phase behavior of polymer blends under shear flow field were reviewed in this paper. There are many molds theoretical model formulations in this research region, such as Wolf Model; Onuki Model; Lyngaae-Jorgensen Model and the Model of the competition of entropy and enthalpy. The contents, scope of application and the advantages and the disadvantages of these models were discussed. And the Wolf Model which is extensively used in the phase behavior of birpolymer blends and terpolymer blends was emphasized in this paper.
