ABSTRACT:
The invention relates to a process for making polyfluorofullerene as well as polyfluorofullerene itself made according to the process.
In the process according to the invention, a fullerene solution is mixed with a polytetrafluoroethylene dispersion, and the reaction mixture is irradiated with fluorescent light to form polyfluorofullerene.
The polyfluorofullerene thus made can be used as oiling agent, lubricant, or as additive for lubricants.
