Graphene foam block, heat-conducting sheet, gasket, arrangement device and preparation method
The invention provides a graphene foam block, a heat-conducting sheet, a heat-conducting gasket, an arrangement device and a preparation method. The preparation method comprises the following steps: arranging a fiber array on a base material; the fiber array is laid flat on the base material in the coating direction; coating the graphene oxide slurry along the horizontal direction; after coating, the fiber array is pulled up in the direction perpendicular to the coating direction, and drying treatment is carried out; repeating the steps of coating, pulling up and drying to obtain a graphene oxide block; and carrying out heat treatment on the graphene oxide block to obtain the graphene foam block. The fibers are seamlessly inserted into the heat-conducting gasket and combined with the graphene stacked layer by layer, the overall structure is complete, no trepanning operation exists in the fiber insertion process, damage to the structural stability is avoided, the mechanical enhancement effect on the graphene heat-conducting gasket can be achieved, it can be guaranteed that the structure is not damaged, and the service life of the graphene heat-conducting gasket is prolonged. And meanwhile, the requirement for preparing gaskets with various thicknesses and sizes can be met.
本发明提供石墨烯泡沫块体、导热片、导热垫片、排布装置及制备方法，所制备方法包括：将纤维阵列排布在基材上；将纤维阵列沿涂布方向在基材上放平；沿放平的方向涂布氧化石墨烯浆料；涂布后，将纤维阵列沿垂直于涂布方向拉起，进行干燥处理；重复涂布、拉起和干燥的步骤，得到氧化石墨烯块体；对上述氧化石墨烯块体进行热处理，得到石墨烯泡沫块体。本发明纤维无缝穿插于导热垫片中，与层层堆叠石墨烯相结合，整体结构完整，纤维穿插过程没有开孔操作，避免其对结构稳定性的破坏，既可以实现对石墨烯导热垫片的力学增强效果，又可以保证其结构不会遭到破坏，同时可以满足制备各种厚度尺寸垫片的要求。
