Application Fields and Prospects of Graphene Powder
Overview: Due to the superior properties of graphene, the potential market size for graphene powder is estimated to exceed one trillion yuan. Currently, the main barriers to the commercialization of graphene are market demand and price. The future industrialization of graphene requires support and innovation from R&D talents. With collective efforts, graphene powder is expected to shine in more fields.
Graphene, a two-dimensional nanocrystal, boasts an exceptional structure that enables outstanding electrical, mechanical, thermal, and optical properties. For instance, it has 100 times the electron mobility of silicon, a strength of up to 130 GPa, excellent flexibility with nearly 20% elongation, high thermal conductivity, a specific surface area of up to 2600 m²/g, and near transparency with an optical absorption rate of only 2.3%. These superior physical properties give graphene powder tremendous application potential in areas such as RF transistors, ultra-sensitive detection sensors, flexible transparent conductive films, high-conductivity composite materials, high-performance lithium-ion batteries, and capacitors.
1. Electronics
Graphene powder, as an electrode material, is an excellent anode material and is considered a potential replacement for silicon wafer materials. Additionally, its applications in flexible screens, wearable devices, solar charging, and other areas are being explored.
2. Thermal Management
The application of metals in thermal management has several challenges, such as difficult processing techniques, high energy consumption, high density, poor conductivity, easy deformation, and waste recycling difficulties. However, applying nano graphene powder to thermally conductive plastics for LED lights and other products can reduce system design costs by at least 30%. Graphene powder, a new nano-composite material composed of single-layer carbon atoms, is highly anticipated across various industries due to its excellent electrical conductivity, thermal conductivity, and heat dissipation properties. Its low-dimensional structure significantly reduces phonon boundary scattering at grain boundaries, leading to unique phonon diffusion modes. Its rapid thermal conduction and heat dissipation capabilities make it an ideal material for cooling in applications such as smartphones, tablets, high-power energy-saving LED lighting, satellite circuits, and laser weapons.
3. Biomedical
Graphene powder exhibits excellent mechanical properties and biocompatibility. As a reinforcing filler, it can significantly enhance the mechanical properties of bioengineering materials.
