Title:
WATER-RESISTANT AND LOW-FRICTION POLYMER COMPOSITE COMPRISING NANO-DIAMOND POWDER TREATED WITH HYDROGEN PLASMA, AND METHOD FOR PRODUCING POLYMER COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2017/135724
Kind Code:
A1
Abstract:
The present invention provides a polytetrafluoroethylene (PTFE) coating agent and a method for producing same. The PTFE coating agent comprises: nano-diamond powder from which non-crystalline carbon has been removed by means of a plasma treatment of the surface thereof with a reaction gas comprising hydrogen, and which has been pulverized from a common diamond state, and the surface of which has a functional group attached thereto; and a PTFE solution for dispersing the nano-diamond powder.
