Graphene is the hardest and thinnest natural material in existence. It has a high transmittance and is so dense that nothing but protons can pass through it, and it moves electrons very quickly, transfers heat very quickly, and has a high carrying capacity for electrical currents. It has a variety of excellent material properties, and has a broad application space in new energy, electronic information, functional materials, new coatings, biomedicine, aerospace, high precision machinery, energy saving and environmental protection. So, what are the multi-industry and multi-performance uses of graphene powder? Here's a look at it!

At present, graphene products are generally divided into two forms: graphene powder and graphene film. Graphene powder is currently used in a wide range of applications such as new energy, anti-corrosion coatings, composite materials and biosensors. This article focuses on graphene powder. Graphene thin films are mainly used in flexible displays and sensors and other fields, and the application range is relatively small. Graphene atomic structure graphene films are well protected by corroded metal and steel structures.

Graphene is used in conventional lithium batteries. As with graphene, many of the raw materials for lithium batteries are nanomaterials. The raw materials for both the positive and negative electrodes are in the form of a powder. The production process requires a slurry to be made, which is applied to the positive and negative electrodes. Carbon nanomaterials are already a well-established conductive agent for batteries. Graphene is used to replace the original conductive agent and improve the performance of the battery without changing the original process configuration.

Graphene for coatings. The application of graphene in coatings is mainly based on its high conductivity, low resistance, high strength and corrosion resistance properties. The products prepared are graphene conductive/heat generating/electromagnetic shielding coatings and graphene anti-corrosion coatings.

1. Graphene conductive/heat generating/electromagnetic shielding coatings. Graphene is the material with the highest thermal conductivity to date and has very good thermal conductivity. On the basis of two-dimensional surface electron conduction, three efficient modes of electron movement are simultaneously realised: webbing, tunneling and magnetic difference. Due to the friction and collision of electron movement, heat is generated and heat conduction is achieved in the form of infrared and surface radiation. The electrical and thermal conversion rate can be over 99%. Graphene conductive/heat generating/electromagnetic shielding coatings made by Microcrystalline Technology using these properties are safe, reliable, energy efficient, fast heating up, uniform heating, good weather resistance, excellent performance and flexible application.

2. Graphene anti-corrosion coatings. Various properties of graphene: flake barrier effect, stacking effect The flake structure of graphene forms a "labyrinthine" shielding structure in the coating structure, which can effectively inhibit the infiltration, penetration and diffusion of corrosive media and improve the physical properties of the anti-corrosion coating. Barriers. "Conductive bridging" mechanism, most of the current traditional anti-corrosion coatings use zinc powder as the active ingredient. However, as the corrosion time increases, the zinc in the coating is oxidised and the electrical conductivity is reduced, which may block the electron transfer path and lose the effect of cathodic protection, causing the coating to lose its anti-corrosion properties. If graphene powder with microcrystalline technology is added to anti-corrosion coatings, the graphene structure gives the coating a good electrical conductivity and forms a long-term stable and more stable electrochemical protection. The 'hydrophobicity' of graphene, combined with its high strength, enhances the stability of the anti-corrosion coating.

Graphene anti-corrosion coatings made from graphene have many advantages: high film strength, high adhesion and good physical and mechanical properties in all aspects. Microcrystalline Technology's graphene anticorrosion coating # anticorrosion coating # anticorrosion performance is excellent, salt spray resistance greatly exceeds the general zinc powder anticorrosion coating 2000 hours, up to 5000-6000 hours. Low specific gravity, not easy to sink, easy to construct. After curing, the surface of the paint film is dense and stable, and the hydrophobic property of graphene isolates the substrate from moisture and air to a considerable extent. The anti-corrosion coating only needs to be cured at room temperature or low temperature, reducing the cost of the construction process.
