NOVELTY - A graphene-based thermally conductive sheet, comprising a graphite heat conducting base layer and forming the auxiliary heat-conducting layer of the graphite heat conducting substrate surface, the graphite heat conducting substrate comprises two layers of graphene. and also equipped with several carbon fibre between two layers of graphene, the carbon-fibre strips are set in parallel; the width is 20~30 mm and the thickness is 100~500 --mu-- m, and the distance between the adjacent carbon-fibre strips is 20~40 mm, and the auxiliary heat-conducting layer is copper foil, aluminium foil, hexagonal boron nitride, beryllium nitride foil, silicon carbide foil any one of glue formed by the outer surface of the auxiliary heat-conducting substrate. The utility model has light weight, good heat conducting effect, especially suitable for making small, microelectronic components of the heat conducting sheet.
