在熔体成型加工过程中赋予高分子制品某种物理功能结构是拓展其应用领域、提升附加值的重要途径。然而，在此过程中如何高效绿色地构筑功能结构是亟待解决的问题。我们改装的高分子熔体“挤出-辊压”装置，能够绿色连续地制备具有交替微层特征的导电各向异性复合材料。基于此，针对微层结构在熔体成型加工过程中构筑的科学问题，拟开展如下工作：①导电填料对共连续不相容高分子共混体系界面的形成、发展以及流变性能的影响; ②模拟挤出和辊压过程中的物理场，在此基础上理解各组分流变特性对不相容共混体系相结构影响; ③“挤出-辊压”作用下导电交替微层结构的形成和演变机制，微层结构和力学性能、电性能的关系; ④导电各向异性微层复合材料对外场响应及其在电磁屏蔽、导热等领域的功能应用。本研究不但能为高分子材料功能结构的简单绿色制备提供新思路，而且能拓展通用高分子材料的功能应用并提升其附加值，具有一定的理论意义和应用前景。

Constructing physically functional structures in polymer articles during melt processing is an important way to expand their application scope and enhance their added value. However, how to green and efficiently construct physically functional structures during processing is an urgent problem needed to be solved. In this project, a home-made “Extrusion-calendaring” machine will be employed to green and continuously fabricate alternating microlayered composites with anisotropically electrical conductivity. In view of the scientific problems concerning the building process of microlayers, the following work will be done: ①influence of conductive filler on the development of interface in incompatible polymer blends as well as their rheological properties; ②simulation the complex physical fields during melt extrusion and calendaring process, influence of rheological properties of each component on the phase behavior in the incompatible systems; ③ mechanisms for the evolution of alternating microlayers during “Extrusion-calendaring” process, the relationship between microlayers and mechanical, electrical properties; ④ the response of such anisotropically electrical conductive composites to external fields as well as their applications in electromagnetic shielding and heat conduction. This project will not only provide new ideas for the functional structure building via easy and green processing method, but also expand the functional application scope of common polymers. At the same time, this project will promote the added value of the common polymers, showing great significance both in academic theory and practical application.
