摘要:

随着柔性电子器件的飞速发展和应用,传统的热管理材料无法满足高导热、高韧性、良好机械适应性的应用需求。具有高导热系数的柔性导热薄膜材料在下一代器件的热管理应用中显示出巨大的潜力,因此引起了广大学者的关注。目前,导热薄膜材料在智能手机、超薄笔记本、柔性可穿戴设备和智能家电设备中均展现巨大的应用潜能。本文从提升填充型导热复合膜的导热性能出发,介绍了填充型导热复合膜的分类和填充型导热复合膜的导热机理。由设计填料构筑低热阻高导热通路和构筑三维导热网络两种思路提升复合膜的导热性能,阐明了填充型导热复合薄膜的研究进展。

Abstract:

With the rapid development and application of flexible electronic devices, traditional thermal management materials cannot meet a requirement of application for high thermal conductance, high toughness, and good mechanical adaptability. Thermally conductive flexible thin film materials with high a thermal conductivity exhibit great potential in thermal management applications for next⁃generation devices and therefore have attracted great attention by many researchers. At present, thermally conductive thin film materials have shown great application potential in smartphones, ultra⁃thin notebooks, flexible wearables, and smart home appliances. This paper introduced the classification of filled polymer⁃based thermal conductive composite films and their thermal conduction mechanisms from the aspects of the improvement in their thermal conductivity. The thermal conductivity of the composite films was improved by designing fillers to construct a low thermal resistance and high thermal conductivity path as well as a three⁃dimensional thermal conduction network. The research progress in the filled polymer⁃based thermal conductive composite films was also reviewed.

Key words: heat conduction, polymer?based thermally conductive film, packing design, build a three?dimensional network
