Teflon fuser member containing fluorinated nano diamonds

1. A fuser member comprising:

a substrate; and

an outermost layer disposed over the substrate, wherein the outermost layer comprises a plurality of fluorinated nano diamond-containing particles dispersed in a fluoroplastic matrix and wherein each particle of the plurality of fluorinated nano diamond-containing particles comprises a chemically active shell layer that is fluorinated over a chemically inert diamond core.

2. The member of claim 1 , wherein the substrate is a belt, a plate, a film, a sheet, or a drelt.

3. The member of claim 1 , wherein the substrate is formed of a material selected from the group consisting of a metal, a plastic, and a ceramic,

wherein the metal comprises a material selected from the group consisting of an aluminum, an anodized aluminum, a steel, a nickel, a copper, and mixtures thereof, and

wherein the plastic comprises a material selected from the group consisting of a polyimide, a polyester, a polyetheretherketone (PEEK), a poly(arylene ether), a polyamide, and mixtures thereof.

4. The member of claim 1 , wherein the chemically active shell layer comprises a sp 2 carbon black and a functional group comprising a quarternized amine, a carboxylated amine or combinations thereof.

5. The member of claim 1 , wherein the plurality of fluorinated diamond-containing particles are present in the outermost layer in an amount of from about 1 percent to about 50 percent by weight.

6. The member of claim 1 , wherein the fluoroplastic matrix comprises a material selected from the group consisting of polytetrafluoroethylene, copolymer of tetrifluoroethylene and hexafluoropropylene, copolymer of tetrafluoroethylene and perfluoro(propyl vinyl ether), copolymer of tetrafluoroethylene and perfluoro(ethyl vinyl ether), copolymer of tetrafluoroethylene and perfluoro(methyl vinyl ether) and combinations thereof.

7. The member of claim 1 , wherein the surface of the outermost layer has a water contact angle of from about 110 degrees to about 150 degrees.

8. The member of claim 1 , wherein the outermost layer has a surface resistivity ranging from about 10 5 ohm/sq to about 10 15 ohm/sq.

9. The member of claim 1 , wherein the outermost layer has a hardness of from about 1H to about 4H measured by a pencil hardness test.

10. The member of claim 1 , wherein the chemically active shell layer comprises a sp 2 carbon black and a functional group comprising —OH, —COOH, —NH 2 , —SO 3 H, alkyl, a carboxylated amine, a quaternized amine or combinations thereof.
