氟化石墨是氟原子插入石墨层间的一种石墨层间化合物，粉末状固体，颜色随氟碳比的提高逐渐由黑变为灰白，直至白色。氟化石墨具有极低的表面能、优异的化学和热稳定性、极好的润滑性能以及超高理论比容量，使其在固态润滑、防腐防污涂料、锂电池和其它应用领域具有良好的应用前景。氟化石墨根据采用原料不同可细分为氟化鱗片石墨、氟化球形石墨、氟化膨胀石墨及氟化纳米石墨等种类。
Fluorographite is a kind of graphite interlayer compound in which fluorine atoms are inserted into graphite layers. Fluorographite is a powder solid, and its color gradually changes from black to gray to white with the increasing of F/C ratio. Fluorographite has been widely used in solid lubrication, corrosion protective and antifouling coatings Li-CF
x batteries and other fields due to the merits of extremely low surface energy, excellent chemical and thermal stability, outstanding lubrication performance and super theoretical specific capacity. Fluorographite can be subdivided into fluorinated flake graphite, fluorinated spherical graphite, fluorinated expanded graphite and fluorinated nano-graphite according to different raw materials.
