摘要
导热绝缘材料是保障微电子设备、电力装备工作效率和稳态运行必不可少的部分,但随着设备功率的提高,目前主流的硅基材料难以满足高集成技术、微电子封装、大功率电力装备等关键技术对材料导热、绝缘以及力学性能的要求,亟待开发下一代导热绝缘材料。聚合物基导热绝缘材料因其优异的绝缘、导热和机械延展等优异特性而被广泛关注,该文主要以聚合物基复合材料内部结构对导热、绝缘及力学性能的影响为基础,分析总结填料种类、含量、填料尺寸以及填料的复合网络对聚合物热导率的影响规律,并对复合材料的结构设计方法及在各领域的应用现状进行全面梳理与总结,为高导热绝缘复合材料的设计与性能优化提供指导,推动其规模化应用。
Thermal-conductive electric-insulating materials are indispensable in ensuring the working efficiency and steady-state operation of microelectronic equipment and power equipment.However,with the increase of equipment power,it is difficult for the current mainstream silicon-based materials to meet the requirements of high-integration technology,microelectronic packaging,high-power power equipment and other key technologies that have requirements for material thermal conductivity,insulation and mechanical properties.It is urgent to develop the next generation of thermal-conductive electric insulating materials.Polymer-based thermalconductive electric-insulating materials have attracted widespread attention due to their excellent insulation,thermal conductivity and mechanical ductility.Based on the influence of the internal structure of polymer matrix composites on thermal conductivity,insulation and mechanical properties,this paper mainly analyzes and summarizes the influence of filler type,content,filler size and the composite network of fillers on the thermal conductivity of polymers.The structural design method of the material and its application status in various fields are comprehensively sorted out and summarized,which provides guidance for the design and performance optimization of high thermal conductivity insulating composite materials and promotes its large-scale application.
