Graphene thermal conductive film is more cost-effective than artificial graphite sheet

At present, in the application direction of graphene, thermal conductive film is the fastest. This is mainly due to the continuous improvement of the performance of consumer electronic products represented by smart phones in recent years. Especially with the advent of 5g era, the demand for heat dissipation of products has further increased.
The thermal conductivity of graphene has been proved to be the best of all single materials. In October 2018, Huawei introduced graphene heat dissipation technology for the first time in its released mate 20 x, which opened the curtain of graphene application in smart phones.
Before graphene heat dissipation technology was applied, smart phones used artificial graphite sheets for heat conduction. However, the raw material of artificial graphite sheet is polyimide film. On the one hand, the material needs to be imported and the cost is high. On the other hand, the thickness of artificial graphite sheet prepared by polyimide film can reach 40 microns at most. If you want to thicken it again, you can only stack it by multiple layers, and the heat conduction effect will also be affected.
Compared with artificial graphite sheet, graphene can be made of all raw materials and no longer need to be imported. At the same time, graphene has better thermal conductivity and customized thickness. For example, the thermal conductivity of single-layer graphene thermal conductive film is similar to that of multi-layer artificial graphite sheet, but the cost is lower and there is room for improvement.
Under the same performance, the price of graphene is cheaper, and the performance of graphene is better at the same price. It is this high cost performance that causes the "resonance" of the industrial chain - the most urgent thing for mobile phone manufacturers to compete.
At present, murui technology, a new material enterprise in the upstream of the industrial chain, has been invested by Xiaomi. It is planned that the monthly production capacity of graphene thermal conductive film can be 100000 square meters by the end of this year, and 10 million mobile phones can be supplied according to the supply of 100 mobile phones per square meter.
According to IDC's report, the global mobile phone shipment in 2019 was 1.371 billion, of which China's mobile phone shipment was about 370 million. With the increase of 5g mobile phone penetration, IDC expects the market scale of graphene thermal conductive film to reach US $2.3 billion in two to three years.
Introduction of graphene thermal conductive film
Graphene has good thermal conductivity. The macro material graphene film is formed by overlapping single graphene. The thermal conductivity is up to 1300W / m · K. The bending resistance and processing performance are better than the current commercial artificial graphite sheet. It can be used as an excellent heat dissipation material for all kinds of electronic equipment.
