Advantages of Graphene Thermal Management Materials

Overview: Graphene has hydrophobic properties, electrical conductivity, and a sheet-like structure. When applied as a coating on a substrate, it forms a dense and strong network that isolates water from the coating, reducing water vapor contact with the substrate.

Graphene’s electrical conductivity also provides cathodic protection, significantly enhancing the protective performance of coatings by more than five times compared to ordinary coatings. The interest in graphene thermal management materials is growing, and their application in coatings has solved many thermal management issues for metal devices across various industries.

Thermal Conductivity and Heat Dissipation in Metal Components: Currently, there are numerous thermal dissipation coatings available industrially, but few can provide both thermal dissipation and anti-corrosion properties. Existing thermal conductive coatings often have poor anti-corrosion performance, leading to corrosion and wear of metal heat dissipation devices, which may require maintenance or replacement multiple times a year, severely reducing production efficiency and increasing costs.

Advantages of Graphene Thermal Management Materials: The WJ-5076 graphene thermal management material, developed using microcrystalline material technology, can be coated on metal workpieces. Graphene and other thermally conductive materials are uniformly distributed within the coating, reducing thermal resistance and enhancing thermal conductivity. Compared to ordinary thermal conductive coatings, graphene thermal management materials significantly increase the thermal conductivity coefficient, reaching up to 20 W/m.K. Additionally, graphene thermal management materials exhibit excellent mechanical properties, outstanding corrosion resistance, and are environmentally friendly and non-toxic.

Applications of Graphene Thermal Management Materials: Graphene thermal management materials are widely used in various metal components, including electronic and electrical parts, LED lamp covers, radiators, generators, automotive components, and more.
