中国科学院宁波材料技术与工程研究所表面事业部功能碳素材料团队开发了一种低成本、工艺简单、且能大规模应用的石墨烯/高分子高导热复合材料的制备方法,将高分子粉体表面均匀包裹上石墨烯纳米片,再通过热压制备成复合材料。通过此工艺,石墨烯能在高分子基底中形成胞室状的三维结构,其复合材料热导率能达到一般熔融混合法产品的两倍。这种方法适用于各类热塑性聚合物,包括聚乙烯、聚乙烯醇、聚偏氟乙烯
Surface Materials Division, Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences Functional carbon materials team developed a low-cost, simple process, and large-scale application of graphene / polymer high thermal conductivity of composite materials, polymer powder The surface of the graphene is evenly coated with the nanosheet, and the composite material is prepared by hot pressing. Through this process, graphene can form a three-dimensional cellular structure in the polymer matrix, the composite material thermal conductivity can reach twice the general melt mixing products. This method is suitable for a variety of thermoplastic polymers including polyethylene, polyvinyl alcohol, polyvinylidene fluoride
