摘要

石墨烯因具有超高的本征热导率,可作为特殊的功能性填料,在导热硅橡胶领域得到广泛研究。然而,石墨烯的比表面积高达2630m2/g,片层间存在π-π键相互作用力和范德华力,使其难以均匀分散到硅橡胶基体中,极大地制约了其在高性能热界面材料中的应用。针对传统的无机填料一般要在较高的填充量下才能有效地提高基体的热导率,介绍了石墨烯在导热硅橡胶中的研究进展,并从石墨烯的分散性问题入手,详细阐述了多种填料协同填充导热硅橡胶的工艺,简要分析了协同填充对导热硅橡胶性能的影响因素,并对石墨烯导热硅橡胶的应用趋势和工作方向进行了展望。

Abstract

Due to its high intrinsic thermal conductivity,graphene can be used as a special functional filler and has been widely studied in the field of thermal conductive silicone rubber.However,the specific surface area of graphene is as high as 2630m2/g,and there are π-π interaction and van der Waals force between graphene sheets,making it difficult to evenly disperse into the silicone rubber matrix,which greatly restricts its application in high-performance thermal interface materials.In view of the traditional inorganic fillers can generally improve the thermal conductivity of the matrix only by a higher filling amount,the research progresses of graphene in the thermal conductive silicone rubber were introduced.Starting from the problem of the dispersion of graphene,the processes that a variety of fillers were used to synergistically fill conductive silicone rubber were expounded.The influencing factors of the synergistic filling on the properties of thermal silicone rubber were analyzed briefly,and the application trend and working direction of graphene thermal silicone rubber were prospected.
