加工过程中高分子材料形态控制的研究进展

ADVANCE IN CONTROLLING OF POLYMER MATERIALS' MORPHOLOGY DURING PROCESSING

高分子材料的性能不仅依赖于大分子的化学结构和链结构,而且在很大程度上依赖于结晶、取向形态及多相体系的相形态。开展高分子材料在加工过程中的热、应力场作用下形态形成、演化、调控及“定构”研究对发展高分子成型加工基础理论、开发高性能化、复合化、多功能化、低成本化及清洁化高分子材料有重要意义。本文简述了加工过程中高分子材料形态控制的研究进展,包括国内外研究现状、存在的问题和我国的差距及未来研究的重要科学问题。

The properties of polymer materials is dependent not only on macromolecular chemical and chain structures, but also, in a great degree, on morphology including crystallization, orientation as well as phase morphology for multi -phase system. It is crucial to study formation, evolution, controlling and especially structuring of polymer materials' morphology under the influences of the complicated thermal and stress fields during processing. This is of high benefit to developing polymer processing theory, improving properties, compounding polymers with various fillers, developing cheap and environmental protection polymer materials. The present article reviews the advance in controlling of polymer materials' morphology during processing, including national and international recent research, problems and differences, and future major work.
