Abstract

A xerographic component having a substrate and thereover a coating with a thiophene-based material is set forth.

Claims (28)

1. A xerographic fuser component comprising:

a) a subtrate comprising a polymer selected from the group consisiting of fluropolymers, choropolymers, silicone rubbers, polyarylenes, ethylene diene propenes, nitrile rubbers and mixtures thereof, and thereon

b) a coating consisting essentially of a thiophene-based polymer material; and

c) a heating member associated with said fuser component.

2. A xerographic fuser component as claimed in claim 1 , wherein said fluoropolymer is selected from the group consisting of a) copolymers of vinylidenefluoride, hexafluoropropylene and tetrafluoroethylene; b) terpolymers of vinylidenefluoride, hexafluoropropylene and tetrafluoroethylene; and c) and tetrapolymers of vinylidenefluoride, hexafluoropropylene and tetrafluoroethylene and a cure site monomer.

3. A xerographic fuser component as claimed in claim 1 , wherein said optionally substituted C 1 -C 4 alkylene radical is selected from the group consisting of a methylene radical, alkyl-substituted methylene radical, 1,2-ethylene radical, 1,2-ethylene radical substituted by C 1 -C 12 -alkyl, 1,2-ethylene radical substituted by phenyl, and a 1,2-cyclohexylene radical.

4. A xerographic fuser component as claimed in claim 3 , wherein said thiophene-based material is a polyethylene dioxythiophene.

5. A xerographic fuser component as claimed in claim 4 , wherein said thiophene-based material is 3,4 polyethylenedioxythiophene.

6. A xerographic fuser component as claimed in claim 1 , wherein said xerographic fuser component further comprises an intermediate layer positioned between said substrate and said thiophene-based material coating.

7. A xerographic fuser component as claimed in claim 6 , wherein said intermediate layer comprises a polymer.

8. A xerographic fuser component as claimed in claim 7 , wherein said polymer is selected from the group consisting of fluoropolymers, chloropolymers, silicone rubbers, polyimides, polyamides, polypropylenes, pethylenes, polybutylenes, polyarylenes, acrylonitriles, polycarbonates, polysulfones, ethylene diene propenes, nitrile rubbers and mixtures thereof.

9. A xerographic fuser component as claimed in claim 1 , wherein said fuser component further comprises an outer coating on said thiophene-based polymer material coating.

10. A xerographic fuser component as claimed in claim 9 , wherein said outer coating comprises a polymer.

11. A xerographic fuser component as claimed in claim 9 , wherein said thiophene-based polymer material coating is an adhesive.

12. A xerographic fuser component as claimed in claim 11 , wherein said adhesive further comprises polystyrene sulfonic acid.

13. A xerographic fuser component comprising:

a) a substrate comprising a flouropolymer selected from the group consisting of i) copolymers of vinylldenefluoride, hexafluoropropylene and tetrafluroenthylene; ii) terpolymers of vinylidenefluroride, hexafluropropylene and tetrafluroethylene; and iii) tetrapolymers of vinylidenefluride, hexafluropropylene, tetrafluroethylene, and a cure site monomer; and thereon

b) a coating consisting essentially of a thiophene-based polymer material; and

c) a heating member associated with said fuser component.

14. A xerographic fuser component as claimed in claim 13 , wherein said thiophene-based material is 3,4 polyethylenedioxythiophene.

15. An image forming apparatus for forming images on a recording medium comprising:

a charge-retentive surface to receive an electrostatic latent image thereon;

a biasable component capable of receiving an electrical bias for charging one of a xerographic fuser component or copy substrate surface;

a development component to apply toner to said charge-retentive surface to develop said electrostatic latent image to form a developed image on said charge retentive surface;

a transfer component to transfer the developed image from said charge retentive surface to a copy substrate; and

a fuser component for fusing said developed image to a surface of said copy substrate, wherein said fuser component, comprises:

a) a substrate comprising a polymer selected from the group consisting of fluropolymers, chlopolymers, silicone rubbers, polyarylenes, ethylene diene propenes, nitrile rubbers and mixtures thereof; and thereon

b) a coating consisting essentially of a thiophene-based polymer material.
