Hydrophobic and oleophobic fuser member

A method of making a fuser member comprising:

• a) reacting a mixture consisting of functionalized polyfluoropolyether, functionalized polybutadiene wherein the functionalized butadiene is selected from the group consisting of:
• an isocyanate polybutadiene, a hydroxyl polybutadiene, a carboxyl acid polybutadiene, an ester polybutadiene, and an epoxy polybutadiene and wherein said polybutadiene is selected from the group consisting of:
• poly(1,3-butadiene), poly(1,4-butadiene), hydrogenated poly(1,3-butadiene) and hydrogenated poly(1,4-butadiene), a solvent, optional conductive particles, and a catalyst to provide a coating composition of functionalized polyfluoropolyether and functionalized polybutadiene in a weight ratio of from about 20 to 80 to about 80 to 20;
• b) coating the coating composition on a substrate comprising a heat resistant resin selected from the group consisting of:
• polyimides, polyaramides, polyether ether ketones, polyether imides, polyphthalamides, polyamide-imides, polyketones;
• polyphenylsulfide, fluoropolyimides, fluoropolyurethanes and polyesters;
• and
• c) curing the coating composition at a temperature of from about 120° C. to about 250° C. for a period of from about 20 minutes to about 120 minutes to form a surface layer wherein the surface layer comprises a hexadecane contact angle of greater than about 50° a water contact angle of greater than about 90°, wherein the fuser member fuses toner particles and forms images on a media substrate.

A fuser member comprising:

• a substrate layer comprising polyimide;
• a silicone layer disposed on the substrate;
• and
• a surface layer disposed on the silicone layer, wherein the surface layer comprises a polymer consisting of functionalized polyfluoropolyether and functionalized polybutadiene, wherein the functionalized butadiene is selected from the group consisting of:
• an isocyanate polybutadiene, a hydroxyl polybutadiene, a carboxyl acid polybutadiene, an ester polybutadiene, and an epoxy polybutadiene and wherein said polybutadiene is selected from the group consisting of:
• poly(1,3-butadiene), poly(1,4-butadiene), hydrogenated poly(1,3-butadiene) and hydrogenated poly(1,4-butadiene), wherein a weight ratio of functionalized polyfluoropolyether/functionalized polybutadiene is from about 20/80 to about 80/20, wherein the surface layer further comprises conductive particles in an amount of from about 1 to about 60 weight percent based on a total weight of the surface layer and wherein the surface layer has a water contact angle of greater than about 90° and a hexadecane contact angle of greater than about 50°, wherein the fuser member fuses toner particles and forms images on a media substrate.
