Carbon fiber material is a fiber material with excellent properties such as high strength, high stiffness, low density and corrosion resistance. Because its main component is carbon, carbon fiber materials have good electrical conductivity.
Carbon fiber itself is a semiconductor material, and its electrical properties depend on its structure and preparation process. -In general, the electrical conductivity of carbon fibers increases with the integrity of their crystal structure and the crystal size. At the same time, the doping element added in the preparation process can also affect the electrical conductivity of carbon fiber.
In applications, carbon fibers are often used as electrode materials, conductive materials or as conductive layers of composite materials. The electrical conductivity of carbon fiber materials can be improved by heat treatment, surface treatment and other methods to meet different application requirements.
