摘要

环氧树脂由于具有优良的机械性能、介电性能以及良好的加工性

在电器封装、电路板、涂料和联合剂等方面得到广泛应用。在电子领域应用时

由于环氧树脂具有较低的热导率

容易在器件运行过程中产生热量积累

导致器件使用寿命大幅缩短。通过向环氧树脂中填充高导热填料

可以极大提高其热导率。本文简单介绍了环氧树脂基导热复合材料的导热机理

重点从多种填料间的协同效应、构建有效3D导热网络两个方面总结了近几年的研究进展

并对未来的发展方向进行了展望。

Abstract

Epoxy resin has been widely used due to its excellent mechanical properties

dielectric properties and good processability

mainly in the fields of electrical packaging

circuit boards

coatings

and combination agents. Because of the low thermal conductivity of the epoxy resin

it is easy to generate heat accumulation during the operation of the device

resulting in a significant reduction in the service life of the device. Therefore

improving the thermal conductivity of epoxy resin is particularly important for their application. By filling high thermal conductive filler into the epoxy resin

the thermal conductivity can be greatly improved. This mini-review briefly introduces the thermal conductivity mechanism of epoxy resin-based thermal conductive composites

focusing on the synergistic effect between various fillers and constructing an effective thermal conductive network

and forecasts its new development direction.
