Due to the superior properties of graphene, the potential market size of graphene powder is at least one trillion yuan. As far as the current situation is concerned, the biggest obstacles to the marketization of graphene are market demand and price. The road to industrialization in the future is far away and requires the support of the government and the pioneering and innovation of R&D personnel. It is believed that through joint efforts, graphene powder will be More areas to shine.

Graphene is a two-dimensional crystal whose unique structure gives it excellent electrical, mechanical, thermal and optical properties. For example, it has ultra-high carrier mobility 100 times that of silicon, strength up to 130GPa, good flexibility and elongation close to 20%, ultra-high thermal conductivity, specific surface area up to 2600m2/g, and Almost transparent, the light absorption rate is only 2.3% in a wide frequency band. These excellent physical properties make graphene powder show great application potential in radio frequency transistors, ultra-sensitive sensors, flexible transparent conductive films, strong and highly conductive composite materials, high-performance lithium-ion batteries, and supercapacitors.

Although graphene powder has not been industrialized on a large scale, the market is very optimistic about its application. According to the current research and development results, graphene powder will be widely used in the following fields in the future.

1. Electronics

As an electrode material, graphene powder is an excellent anode material and is considered to be a chip material that can replace silicon. In addition, applications in flexible screens, wearable devices, solar charging and other fields are yet to be explored.

2. Heat dissipation

There are many problems in the application of metal in heat dissipation, such as difficult processing, high energy consumption, excessive density, poor electrical conductivity, easy deformation, and difficulty in recycling waste. There is almost no room for price reduction. However, if the nano-graphene powder thermal conductive plastic is applied to the heat dissipation of products such as LED lamps, the system cost can be reduced by at least 30%. Graphene powder is a new type of nanomaterial with a single-layer sheet structure composed of carbon atoms. All walks of life have high hopes for it because of its excellent electrical, thermal and thermal properties. It is a two-dimensional single-layer carbon atomic crystal. Compared with three-dimensional materials, its low-dimensional structure can significantly reduce phonon scattering at grain boundaries, giving it a special phonon diffusion mode. The rapid heat conduction and heat dissipation characteristics make it an excellent heat dissipation material, which can be used for heat dissipation of smart phones, tablet computers, high-power energy-saving LED lighting, satellite circuits, laser weapons, etc.

3. Biomedicine

Graphene powder has excellent mechanical properties and biocompatibility. As a reinforcing filler, it can significantly improve the mechanical properties of biomaterials.
