摘要:电子产品日渐突出的散热问题，引起了人们对电子领域热管理的广泛关注。柔性导热材料具有高韧性、高弹性、高导热、灵活性等特性，可运用于柔性电子器件，轻、薄型电子设备，电池等领域，帮助解决其散热问题。纸张及薄膜具有良好的柔韧性、优异的加工性和厚度可调整性，是良好的柔性导热材料。本文概述了近年来导热纸（膜）的研究进展，对不同基材的导热纸进行了归纳分类和介绍，重点讨论了纤维素基导热纸的制备方法、导热性能、导热性能测试方法及机械性能。

Abstract:The heat dissipation problem of electronic products is increasing， and it has attracted wide spread attention to thermal management in the electronic field. Flexible and thermally conductive materials have the characteristics of excellent toughness， elasticity， thermal conductivity and flexibility， etc. It can be applied in flexible electronic devices， light and thin electronic devices， batteries and other fields to help solve the heat dissipation problems. Paper or film is flexible， simple to produce and the thickness is adjustable， which is a kind of wonderfully flexible and thermally conductive materials. The research progress of thermally conductive paper （film） in recent years was reviewed in this paper. The thermally conductive papers with different substrates were summarized and introduced. The preparation methods， thermal conductivity， measurement for the thermal conductivity and mechanical properties of the cellulose-based paper and film was highlight and discussed.
