Graphene is widely used in functional fibers, heat generation, heat dissipation and other fields, and the demand is huge. Among them, graphene heating products are expected to gradually become mainstream heating products, thereby squeezing the market share of carbon fiber, carbon crystal, and metal composite wire. With the large-scale construction of 5G, the coverage of 5G networks will drive the growth of the demand for smart terminal equipment, and the demand for radiators such as mobile phone cooling, various electrical appliances and even satellite cooling will also greet massive growth.
