摘要：
Disclosed is a polytetrafluoroethylene coating agent having low friction and high wear resistance, obtained by dispersing nanodiamond powder in a polar organic solvent, stirring the nanodiamond dispersion solution and a silane coupling agent, and stirring the silane-treated dispersion solution and an oily polytetrafluoroethylene coating solution, in which the silane coupling agent has at least one organic functional group selected from, but not limited to, a mercapto group and an amino group, the organic functional group exhibiting high bondability to polytetrafluoroethylene. A method of preparing the polytetrafluoroethylene coating agent and a method of using the polytetrafluoroethylene coating agent are also provided.
