ABSTRACT The majority of polymers are electrical and thermal insulators. In order to create electrically active and thermally conductive polymers and composites, the hybrid-filler systems is an effective approach, i.e. combining different types of fillers with different dimensions, in order to facilitate the formation of interconnected conducting networks and to enhance the electrical, thermal, mechanical and processing properties synergistically. By tailoring polymer-filler interactions both thermodynamically and kinetically, the selective localisation of fillers in polymer blends and at the interface of co-continuous polymer blends can enhance the electrical conductivity at a low percolation threshold. Moreover, selective localisation of different filler types in different co-continuous phases can result in multiple functionalities, such as high electrical conductivity, thermal conductivity or electromagnetic interference shielding. In this review, we discuss the latest progress towards the development of electrically active and thermally conductive polymer composites, and highlight the technical challenges and future research directions.

定制多组分和多相聚合物复合材料的导电性和导热性

摘要 大多数聚合物是电绝缘体和热绝缘体。为了创造导电和导热的聚合物和复合材料，混合填料系统是一种有效的方法，即结合不同类型的不同尺寸的填料，以促进互连导电网络的形成并增强电、热, 机械和加工性能协同。通过在热力学和动力学上调整聚合物-填料的相互作用，填料在聚合物共混物和共连续聚合物共混物的界面处的选择性定位可以在低渗透阈值下提高电导率。此外，不同共连续相中不同填料类型的选择性定位可以产生多种功能，如高导电性、导热性或电磁干扰屏蔽。在这篇综述中，我们讨论了电活性和导热聚合物复合材料的最新进展，并强调了技术挑战和未来的研究方向。
