On December 13, 2021, China's leading high-performance graphene heat dissipation film manufacturer: SZJF Electronic Materials Technology Corporation announced that the company will invest 1.3 billion yuan in the construction of a new production base for high-performance graphene heat dissipation film.
The "high-performance graphene heat dissipation film" developed by SZJF has the characteristics of good mechanical performance, high thermal conductivity, light weight, and good flexibility. It is widely used in smart phones, tablet computers, fanless design notebook computers, LED lighting equipment, Medical equipment, new energy vehicle power batteries and other fields.
It is understood that graphene has excellent heat dissipation performance, and its thermal conductivity is 800~5300W/m·K, which is the material with the highest thermal conductivity known. The graphene heat dissipation film is very thin, flexible, and has excellent comprehensive performance, which provides the possibility for the thinner development of electronic products.
Secondly, the graphene heat dissipation film has good reworkability and can be composited with other film materials such as PET according to the application. In addition, this kind of heat conduction material is elastic, can be cut and punched into any shape, and can be bent many times; it can convert a point heat source into a surface heat source for rapid heat conduction, has high thermal conductivity, and is a very competitive heat dissipation. Material.
In October 2018, Huawei used the high-performance graphene heat dissipation film developed by SZJF as its main heat dissipation solution for the first time in the Mate20 series of mobile phones. "xiaomi10" and other consumer electronic products have been more and more used.
