摘要
石墨烯是一种新型的二维纳米材料,可以提供声子的二维传播路径,具有非常优异的导热性能,是导热型聚合物复合材料的理想填料。文中总结了石墨烯/聚合物复合材料导热性能的影响因素(石墨烯取向、石墨烯尺寸、温度、聚合物链长度、石墨烯片层厚度、石墨烯分散性和与聚合物的界面强度),重点介绍了3种增强石墨烯/聚合物复合材料导热性能的方式(共价键连接、非共价键连接、多种填料协同共混)。
Graphene is a new type of two-dimension nanomaterials, which can supply the two-dimensional transfer route for phonon. Due to excellent thermal conductivity, graphene is the ideal filler for thermal-conductive polymer- based nanocomposites. In this review, the influence factors of thermal conductivity of graphene/polymer composites were summarized, such as the oriention of graphene, the size of graphene, temperature, the length of polymer chain, the thickness of graphene, the dispersion of graphene and the interracial strength between graphene and polymer. Some methods in improving thermal conductibility of graphene-reinforced composites were introduced, such as covalent bonding, non-covalent bonding and synergetic effects of various fillers.
