摘要
5G时代的到来刺激了密集集成化的大功率电子器件的快速发展.三维导热网络因其卓越的导热性和导电性,以及可调节的结构特性,被认为是提高电子器件性能的可行关键材料.本综述介绍了碳基三维导热网络的重要概述,强调了炭材料之间的制备-结构-性能关系及其在不同场景中的应用.首先,详细讨论了热导率的微观原理,这是指导三维炭材料热导率增强的关键因素.此外,深入研究了利用石墨烯、泡沫炭和碳纳米管等不同炭材料构建三维网络的方法.重点介绍了将二维石墨烯组装成三维石墨烯网络的制备技术及其对导热性能的影响.最后,提出了碳基三维导热网络存在的挑战和发展前景.该综述为下一代三维碳基导热网络材料的设计和构建提供参考.
Abstract
The advent of the 5G era has stimulated the rapid development of high power electronics with dense integration.Three-dimensional(3D)thermally conductive networks,possessing high thermal and electrical conductivities and many different structures,are regarded as key materials to improve the performance of electronic devices.We provide a critical overview of carbon-based 3D thermally conductive networks,emphasizing their preparation-structure-property relationships and their applications in dif-ferent scenarios.A detailed discussion of the microscopic principles of thermal conductivity is provided,which is crucial for increas-ing it.This is followed by an in-depth account of the construction of 3D networks using different carbon materials,such as graphene,carbon foam,and carbon nanotubes.Techniques for the assembly of two-dimensional graphene into 3D networks and their effects on thermal conductivity are emphasized.Finally,the existing challenges and future prospects for 3D carbon-based thermally conductive networks are discussed.
