摘要:

2004 年石墨烯的发现立刻引起了全球科技界的高度关注, 掀起了从碳纳米管问世以来对于碳族材料的又一个研究高潮, 人们迅速开展了针对石墨烯的制备、性能表征、甚至应用的研究工作. 从石墨烯问世到目前, 主要研究工作集中在石墨烯电学性能的研究, 特别是集中在用石墨烯制备超级电容器方面. 相比之下, 人们对于石墨烯热学性能的研究还比较少. 然而, 鉴于石墨烯具有极高的热导率和负的热膨胀系数, 以及作为热界面材料的工程应用价值, 对其热学性能的研究正逐渐成为研究的一个重要分支. 以石墨烯热学性能如热导率到热膨胀系数为研究对象, 全面总结国际上的发展现状. 内容涉及单层石墨烯、多层石墨烯和石墨烯泡沫. 研究手段包括理论研究、数值模拟和实验测定3 个方面. 在综合研究成果的基础上, 最后对于存在的问题和可能的发展方向给出了合理的建议.

Abstract:

Graphene has attracted the attention of scientific world immediately since its discovery in 2004, and raises a research wave of carbon allotrope after the finding of carbon nanotubes. A series of research works were carried out from graphene fabrication and characterization, even to possible application. From the appearance of graphene, main works were concentrated on its electric properties, especially on the supercapacitor. Comparatively, the study on its thermal properties is seldom. However, due to its extremely high thermal conductivity and negative coefficient of thermal expansion, as well as value of engineering application, the research work on its thermal properties is becoming one of hot points. In this paper, an overall review is completed on the achievements in the world about thermal properties of graphene such as thermal conductivity and coefficient of thermal expansion. It concerns single layer, multilayer graphene and graphene foam, and presents the results obtained by experiments, theories and numerical simulations. Based on the review, it finally
reveals the existing problems and proposes the possible solutions for future development.
