Research Progress in Preparation of Lignin-based Carbon Fiber

Lignin is rich in nature, it is also renewable and with high carbon content. The application of lignin in the preparation of carbon fiber has an unparalleled cost advantage.The development of lignin-based carbon fiber is briefly introduced. The progress of the source, structure difference and carbon fiber preparation methods of kraft lignin, organosolv lignin and steam-explosion lignin is discussed in detail. As a result, the kraft lignin has been chosen as the best raw material for the preparation of low cost carbon fiber. Furthermore, the future direction of lignin-based carbon fiber is pointed out, which aims to provide reference for the initial research of lignin-based carbon fiber.
