英文摘要	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.; Graphene has attracted the attention of scientific community immediately since its discovery in 2004, and raised a research wave of carbon allotrope after the finding of carbon nanotubes. A series of research works have been carried out on graphene fabrication, characterization and possible applications. Since its appearance, most studies have been concentrated on its electric properties, especially on the supercapacitor. Comparatively, there are fewer studies on its thermal properties. However, due to its extremely high thermal conductivity and negative coefficient of thermal expansion, as well as its value for engineering application, research on its thermal properties is becoming one of hot topics. In this paper, we overview the achievements in the world about thermal properties of graphene such as thermal conductivity and coefficient of thermal expansion. We are concerned with single layer and multilayer grapheme, and graphene foam. We present results obtained from experiments, theories and numerical simulations. Based on the review, we raise some existing problems, and propose possible solutions for future development. ? 2014 Advances in Mechanics.; EI; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 1; 236-259; 44
