Which is better, graphene thermal patch or graphite thermal patch?

Graphene is known to have the highest thermal conductivity. The theoretical thermal conductivity of graphene reaches 5300W/m? K is a common heat conducting material Cu(40 1W/m? K) is more than 13 times, much higher than graphite. Graphene is an excellent heat dissipation material with fast heat conduction and heat dissipation, which can be used in smart phones, tablet PDAs, high-power energy-saving LED lighting, super LCD TVs and so on.

Graphite heat dissipation technology is widely used because of its high thermal conductivity and relatively low cost and easy production. Many brands, including iPhone, LG, Xiaomi and ZTE, have applied graphite heat dissipation technology to their mobile phones.

Compared with graphite, graphene has superior heat dissipation performance. The heat dissipation performance of the heat dissipation film made of graphene is much better than that of graphite sheet. Guizhou New Carbon Hi-Tech Co., Ltd. launched China's first pure graphene powder product-flexible graphene cooling film. The appearance of graphene heat dissipation film is similar to tin foil paper, which is flexible and can be folded at will and cut into any shape with scissors. The film thickness is controlled at about 25 microns, which is equivalent to one third of ordinary A4 paper. According to the certification of the organization, compared with the commonly used copper heat dissipation material, the heat dissipation effect of this product will be improved by 4-6 times, and it has good machinability.
