Sintered graphene foam block reinforced graphene heat-conducting gasket and preparation method thereof
The invention provides a preparation method of a sintered graphene foam block reinforced graphene heat-conducting gasket. The preparation method comprises the following steps: preparing graphene carbonized films; stacking the graphene carbonized films, and sintering to prepare a highly oriented graphene foam block; and slicing the graphene foam block in the longitudinal direction to obtain the graphene heat conduction gasket, wherein the longitudinal direction is the stacking direction of the multiple graphene carbonized films. The invention also provides the graphene heat-conducting gasket. The sintered graphene foam block reinforced graphene heat-conducting gasket is free of adhesive compounding, and has the advantages of low density and high thermal conductivity in the thickness direction.
本发明提供一种烧结石墨烯泡沫块增强的石墨烯导热垫片的制备方法，包括：制备石墨烯碳化膜；将多片石墨烯碳化膜堆叠，进行烧结，制备高定向石墨烯泡沫块；沿纵向将石墨烯泡沫块进行切片，得到石墨烯导热垫片，所述纵向为多片石墨烯碳化膜的堆叠方向。本发明还提供石墨烯导热垫片。本发明无胶黏剂复合，具有低密度、厚度方向高导热的优点。
