Flexible high-electric-conductivity and high-heat-conductivity ceramic-based composite film and preparation method thereof
The invention relates to a flexible high-electric-conductivity and high-heat-conductivity ceramic-based composite film which is prepared by the following method: adding a sintering aid into ceramic powder to prepare a base material; taking diamond particles, and condcuting coating to prepare coated diamond particles; taking graphene nanosheets and copper particles for later use; mixing the base material, the coated diamond particles, the graphene nanosheets and the copper particles into slurry, and then preparing a composite film blank by adopting a tape casting process; or using the base material, the coated diamond particles, the graphene nanosheets and the copper particles to prepare a base film blank, a diamond film blank, a graphene film blank and a copper film blank respectively; and putting the composite film blank into a mold, and conducting sintering and molding to obtain the ceramic-based composite film. The problem that high thermal conductivity and high flexibility of a macroscopic material cannot be considered at the same time is well solved.
本发明涉及一种柔性高导电导热陶瓷基复合薄膜，其采用以下方法制备：在陶瓷粉末中加入烧结助剂，制成基体材料；取金刚石颗粒进行镀膜，制成覆镀金刚石颗粒；取石墨烯纳米片和铜颗粒备用；将基体材料、覆镀金刚石颗粒、石墨烯纳米片和铜颗粒混合成浆料，然后采用流延成型工艺制成复合薄膜坯料；或者，将所述基体材料、覆镀金刚石颗粒、石墨烯纳米片和铜颗粒分别制成基体薄膜坯料、金刚石薄膜坯料、石墨烯薄膜坯料、铜薄膜坯料；将所述复合薄膜坯料放入模具中，然后烧结成型，得到陶瓷基复合薄膜。本发明很好地解决了宏观材料高导热和高柔性不能兼顾的难题。
