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 depend not only on the chemical structure and chain structure of the macromolecules, but also on the crystal morphology, orientation morphology and phase morphology of the multiphase system. Development, formation, evolution, regulation and control of “formation” under the action of heat and stress in the process of polymer materials To develop the basic theory of polymer forming and processing, and to develop high performance, compound, multifunctional, low cost It is important to clean and clean the polymer materials. This article briefly reviews the research progress of morphological control of polymer materials during processing, including the research status quo at home and abroad, the existing problems and the disparity in our country and the important scientific problems for future research.
