Abstract

Today, electronic components are gradually developing towards miniaturization and multi-function. During the use of electronic components, a large amount of heat will be generated, which seriously limits the performance and service life of electronic components. Therefore, the preparation of thermal management material (TMMs) with high thermal conductivity (λ) can effectively solve the problem of thermal accumulation in electronic components. Compared with the preparation of intrinsic thermal conductive polymer composite, the method of filling thermal conductive filler in polymer matrix can better improve the λ of polymer composite. This review discusses the heat conduction mechanism of polymer and the factors affecting λ of polymer composites, including the type of filler, the shape and distribution of filler, and the functional surface treatment of filler. Then, the different methods of preparing thermally conductive and electrically insulating polymer composites (TCEIPCs) are introduced in detail. The application of polymer composites in thermal management is also introduced.

导热与电绝缘聚合物复合材料在热管理材料中的制备、机理及应用研究进展

当今，电子元器件正逐步向小型化、多功能化方向发展。电子元器件在使用过程中会产生大量的热量，严重限制了电子元器件的性能和使用寿命。因此，制备具有高导热系数(λ)的热管理材料(TMMs)可以有效地解决电子元件中的热积累问题。与制备本征导热聚合物复合材料相比，在聚合物基体中填充导热填料的方法能更好地提高聚合物复合材料的λ。本文综述了聚合物的导热机理和影响聚合物复合材料λ的因素，包括填料的种类、填料的形状和分布、填料的表面功能处理等。然后详细介绍了导热和电绝缘聚合物复合材料的不同制备方法。介绍了高分子复合材料在热管理中的应用。

期刊介绍： Health Services Management Research (HSMR) is an authoritative international peer-reviewed journal which publishes theoretically and empirically rigorous research on questions of enduring interest to health-care organizations and systems throughout the world. Examining the real issues confronting health services management, it provides an independent view and cutting edge evidence-based research to guide policy-making and management decision-making. HSMR aims to be a forum serving an international community of academics and researchers on the one hand and healthcare managers, executives, policymakers and clinicians and all health professionals on the other. HSMR wants to make a substantial contribution to both research and managerial practice, with particular emphasis placed on publishing studies which offer actionable findings and on promoting knowledge mobilisation toward theoretical advances. All papers are expected to be of interest and relevance to an international audience. HSMR aims at enhance communication between academics and practitioners concerned with developing, implementing, and analysing health management issues, reforms and innovations primarily in European health systems and in all countries with developed health systems. Papers can report research undertaken in a single country, but they need to locate and explain their findings in an international context, and in international literature.
