摘要:

基于连续辊压⁃空间限制域强制组装法(continuous roll⁃spatial⁃spatial confining forced network assembly, CR⁃SCFNA)开发了一种聚合物复合材料连续强制组装加工设备。该设备的核心是分级辊压装置,它能够逐步将复合材料的厚度压缩至与限域板相匹配的尺寸。结果表明,利用强制组装力,即径向压力与垂直于径向的剪切力可以促进填料在聚合物基体中的高密度排列和定向组装,构建出一个密实的导热/导电强制组装网络。这一创新工艺显著提升了聚合物复合材料的热传导和电传导性能,满足了现代工业对高性能材料的迫切需求。

Abstract:

Continuous roll⁃spatial confining forced network assembly (CR⁃SCFNA) innovatively reengineers the traditional flat⁃plate hot⁃pressing method into a dynamic “flexible roll⁃to⁃plate” process. By integrating the mechanical force of rollers with the intrinsic self⁃assembly behavior of fillers, CR⁃SCFNA synergistically drives the formation of a high⁃density filler network. The system employs a graded roller press that progressively compresses the composite material to align with the dimensional specifications of the limit plate. Experimental results demonstrated that applying forced assembly forces, specifically radial compression combined with orthogonal shear forces, enabled precise alignment and directional organization of fillers within the polymer matrix. This created a densely interconnected thermally/electrically conductive network. This breakthrough process significantly enhances the thermal and electrical conductivity of polymer composites, addressing the growing industrial demand for lightweight, high⁃performance materials in applications such as electronics, energy systems, and advanced manufacturing.
