Claims11
A composite material comprising:
- (A) polyimide substrate and
- (B) a coating layer comprising a binder resin and a solid lubricant,
- wherein at least a part of the surface of the polyimide substrate is covered by the coating layer, and wherein the amount of a solid lubricant is from 50 to 90 weight % based on the weight of the coating layer.
An article comprising polyimide, in which at least a part of the surface of the article is covered by an anti-friction coating comprising a binder resin and a solid lubricant wherein the amount of a solid lubricant in the anti-friction coating is from 50 to 90 weight % based on the weight of the anti-friction coating.
A sliding structure comprising a first part made from polyimide and a second part made from a metal, the first part and the second part are contacted each other, at least one of the surface of the two parts is covered by a coating layer, wherein the coating layer comprises (A) polyimide substrate and (B) a coating layer comprising a binder resin and a solid lubricant wherein the amount of a solid lubricant in the coating layer is from 50 to 90 weight % based on the weight of the coating layer.
