    Graphene Nanopowders List

    Graphene has excellent optical, electrical, and mechanical properties in materials science. Micro-nano processing, energy, biomedicine, and drug delivery have important application prospects and are considered to be a revolutionary material in the future. Graphene nanopowders refers to the nanometer level (1-100nm) graphene microscopic particles. Nanoparticles have important scientific research value. They build bridges between bulk matter and atoms and molecules. It can be seen that graphene nanopowders have some novel physical and chemical properties.

    • Ceramic materials: Experiments have shown that when traditional materials such as carbon nanotubes, one-dimensional carbon fibers and ceramic whiskers are combined with ceramics, it is difficult to uniformly disperse in the ceramic matrix, but graphene nanopowders do not. Moreover, the excellent physical and chemical properties of graphene nano-powders can significantly improve the mechanical, electrical and thermal properties of graphene ceramic composites. The brittleness and insulation properties of the ceramics can be completely changed, and a special graphene ceramic composite can finally be obtained. And high-purity graphene nanopowder can be used as a fine ceramic material. It has the ability to be hard, wear-resistant, high temperature resistant and corrosion resistant, and some ceramic materials have energy conversion and information transmission functions.
    • Hydrogen storage materials: Graphene has the advantages of light weight, high chemical stability and high specific surface area, making it the best candidate for hydrogen storage materials. The graphene nanopowder has small particles and a large specific surface area, which can better absorb hydrogen, which greatly improves its hydrogen storage capacity and has better stability than traditional graphene hydrogen storage materials.
    • Purification system: Graphene nanopowders has a super high specific surface area, which can adsorb toxic and harmful substances. The adsorption capacity can reach hundreds of times its own weight. After adsorption, it can be recycled after treatment. The surface of the ordinary sponge is evenly covered with a graphene nanopowders coating, which uses its conductive, hydrophobic, and lipophilic characteristics to absorb the floating oil that leaks on the sea.
    • Anti-rust coating: Since graphene is not soluble in water, it can be mixed with polymers for anti-rust coating. The particles of graphene nanopowders are small and uniform, and the anti-rust coating can be thin and uniform. Graphene is insoluble in water and highly conductive. If combined with steel, it can prevent steel from contacting water and ease the electrochemical reaction of iron oxide.
    • Functional composite materials: Adding graphene nanopowders to various shaping groups can prepare special materials with good electrical conductivity, heat conduction, processability, and damage resistance. They are application potential in integrated circuits, heat sinks, and high-toughness containers.
