Abstract
A fuser comprises a substrate and a composite layer formed on the substrate. The composite layer comprises a fluoropolymer and at least one of (a) perfluorosulfonated polymer-treated, carbon nanotube-comprising particles, and (b) perfluorosulfonated polymer-treated, graphene-comprising particles. Methods of making a fuser and methods of fusing toner particles are also disclosed.
Claims20
A fuser comprising:
- a substrate;
- and
- a composite layer formed on the substrate, the composite layer comprising a fluoropolymer and at least one of (a) perfluorosulfonated polymer-treated, carbon nanotube-comprising particles, and (b) perfluorosulfonated polymer-treated, graphene-comprising particles.
A method for making a fuser, the method, comprising:
- providing a substrate;
- flowcoating a coating composition onto the substrate, the coating composition comprising:
- a liquid continuous phase;
- and
- a plurality of composite particles dispersed in the liquid continuous phase, the composite particles each comprising a fluoropolymer and at least one of (a) perfluorosulfonated polymer-treated, carbon nanotubes-comprising particles and (b) perfluorosulfonated polymer-treated, graphene-comprising particles;
- and
- heating the coating composition on the substrate at a baking temperature to form a fuser outer layer.
The method of 15, wherein the fluoroplastic resin is selected from the group consisting of is selected from the group consisting of polytetrafluoroethylene (PTFE), perfluoroalkoxy polymer resin (PFA), poly(tetrafluoroethylene-co-perfluoropropyl vinyl ether), fluorinated ethylenepropylene copolymer (FEP), and a combination thereof.
A method of fusing toner particles to a substrate, the method comprising:
- providing a print substrate;
- forming an image of toner particles on the print substrate;
- and
- contacting the toner particles on the print substrate with a fuser roll heated to a fusing temperature to permanently affix the image to the substrate, the fuser roll comprising a fuser substrate and a composite layer formed on the fuser substrate, the composite layer comprising a fluoropolymer and at least one of (a) perfluorosulfonated polymer-treated, carbon nanotubes-comprising particles and (b) perfluorosulfonated polymer-treated, graphene-comprising particles.
