Abstract
Provided are a polytetrafluoroethylene (PTFE) coating and a preparing method of the same. The PTFE coating includes: a nanodiamond powder whose surface is treated with a plasma using a hydrogen-containing reactive gas to remove amorphous carbon, the nanodiamond powder being ground in a commercially available state and having a surface to which a functional group is attached; and a PTFE solution dispersing the nanodiamond powder.

A polytetrafluoroethylene (PTFE) coating comprising:
- a nanodiamond powder whose surface is treated with a plasma using a hydrogen-containing reactive gas to remove amorphous carbon, the nanodiamond powder being ground in a commercially available state and having a surface to which a functional group is attached;
- and
- a PTFE solution dispersing the nanodiamond powder.
A preparing method of a polytetrafluoroethylene (PTFE) coating, comprising:
- treating a commercially available diamond powder with a plasma using a hydrogen-containing reactive gas to be ground to a nanodiamond powder, remove amorphous carbon on a surface of the plasma-treated nanodiamond powder, and attach a functional group to the surface of the plasma-treated nanodiamond powder;
- and
- mixing the plasma-treated nanodiamond with a PTFE solution
