Fluorinated carbon is one of the research hotspots of new graphite materials with high performance and high efficiency in the world. As a high-tech functional material, fluorinated carbon has a series of unique physical and chemical properties, and its application range can be expected to continue to expand. In addition to being used as a cathode material, fluorinated carbon is used as a solid lubricant. Graphite fluoride is particularly suitable for use under harsh conditions such as high temperature, high pressure, high speed, high load and corrosive media. The lubrication performance is greatly improved by adding fluorinated carbon to the lubricating grease. At the same time, the lubricating grease of modified graphite fluoride has good lubrication performance and excellent wear resistance, which is especially suitable as an anti-wear agent for copper-to-steel friction parts. Given the rich performance characteristics of fluorinated carbon, they also have been widely studied in industries such as biomedical, hydrophobic materials, surface coatings, phototherapy, etc. In this chapter, we will describe its applications separately.
