Graphene films have huge room for development in the fields of heat dissipation and display, and the industry scale continues to expand.

Graphene film is a large-area single crystal or polycrystalline graphene film material prepared by spin coating, spray coating, chemical vapor deposition and other processes. Graphene film has good mechanical properties, flexibility, thermal conductivity, electrical conductivity, electron mobility, light transmittance and other characteristics, and can be widely used in smartphones, tablets, computers, display panels, wearable smart devices, and medical equipment , precision instruments, power batteries and other fields.

Graphene is a strategic emerging material. Research on its technology and applications continues to deepen, and the capital entering the layout continues to increase. However, the price of graphene is high, and its commercial application is not ideal, and many companies are in a state of loss. As technology continues to make breakthroughs, the price of graphene continues to decline, and its application demand is gradually increasing. At this stage, graphene films have been widely used in the field of consumer electronics heat dissipation. In addition to heat dissipation, graphene films can also be used in flexible displays, integrated circuits, sensors, etc.

In terms of heat dissipation, graphene film has the characteristics of high thermal conductivity and high flexibility, and the thickness of the product is thin, which can meet the high heat dissipation requirements under the development of integrated and thin consumer electronics functions, and can be used in foldable mobile phones, wearable devices, etc. In scenes that require high material flexibility. Currently, smartphones are an important application market for graphene heat dissipation films. Since 2018, many smartphones from Huawei, Xiaomi and other mobile phone manufacturers in my country have adopted graphene films as the main heat dissipation solution.

According to the “In-depth Market Research and Investment Strategy Suggestions Report on Graphene Film Industry 2021-2025” released by the Industrial Research Center, consumption The high-end development of electronics will promote the continued growth of demand for graphene films in the heat dissipation field. It is expected that by 2023, the global graphene film market size in the heat dissipation field will reach approximately US$2.32 billion. In addition to the heat dissipation field, the flexible display field will be another important downstream market for graphene films. As a flexible transparent conductive film with excellent performance, graphene film is expected to replace the inflexible ITO (indium tin oxide) film and has great market potential in the future. .

my country’s graphene film manufacturers mainly include 2D Carbon, Moxi Technology, Microcrystalline Technology, Sixth Element, etc., which are capable of mass-producing graphene heat dissipation films, graphene transparent conductive films and other products. Attracted by market prospects, the scale of my country’s graphene film industry continues to expand. In December 2021, Jinfu Technology announced that the company plans to issue shares to specific targets to raise a total of no more than 738 million yuan, which will be used for the construction project of a high-performance graphene cooling film production base and to supplement working capital.

Industry analysts said that in addition to the fields of heat dissipation and flexible display, integrated devices made by combining transistors and other components on graphene films Circuits can realize the production of ultra-high energy-efficiency flexible and transparent electronic devices; using graphene films as materials to manufacture sensors can use CMOS processing technology, which greatly reduces the cost during large-scale mass production, and the products are more sensitive and have lower power consumption. From the perspective of multiple downstream application fields, graphene film market space is huge and the future industry development prospects are broad.
