Due to the characteristics of low surface energy and strong chemical inertness, the application of fluorinated carbon fiber is limited. Low degree of surface fluorination can improve the surface energy of carbon fiber and greatly improve its wettability and adhesion, while high degree of surface fluorination can further reduce its surface energy and enhance its lubricity and dispersion in solution, thus greatly expanding other application fields. Fluorinated carbon fiber can be used as insulator, active materials for battery, light and high conductivity materials.
