Abstract
In accordance with the invention, there are printing apparatuses, fuser members, and methods of making fuser members. The printing apparatus can include a fuser member, the fuser member including a substrate. The fuser member can also include one or more functional layers disposed over the substrate and a top coat layer including a fluorinated nanocomposite disposed over the one or more functional layers, wherein the fluorinated nanocomposite includes a plurality of fluorinated carbon nanotubes dispersed in one or more fluoropolymers.
Claims18
A printing apparatus comprising:
- a fuser member, the fuser member comprising a substrate;
- one or more functional layers disposed over the substrate;
- and
- a top coat layer comprising a fluorinated nanocomposite disposed over the one or more functional layers, wherein the fluorinated nanocomposite comprises a plurality of fluorinated multi-walled carbon nanotubes dispersed in one or more fluoropolymers selected from the group consisting of perfluoroalkoxycopolymer, poly(tetrafluoroethylene), fluorinated ethylene-propylene copolymer, and combinations thereof, and wherein the top coat layer comprises a thickness ranging from about 10 micron to about 75 micron.
A method of making a member of a fuser subsystem, the method comprising:
- providing a fuser member, the fuser member comprising a substrate;
- forming one or more functional layers over the substrate;
- and
- forming a top coat layer comprising a fluorinated nanocomposite over the one or more functional layers, wherein the fluorinated nanocomposite comprises a plurality of fluorinated multi-walled carbon nanotubes dispersed in one or more fluoropolymers selected from the group consisting of perfluoroalkoxycopolymer, poly(tetrafluoroethylene), fluorinated ethylene-propylene copolymer, and combinations thereof, and wherein the top coat layer comprises a thickness ranging from about 10 micron to about 75 micron.
A method of forming an image comprising:
- providing a toner image on a media;
- providing a fuser subsystem comprising a fuser member, the fuser member comprising one or more functional layers disposed over a substrate and a top coat layer comprising a thickness ranging from about 10 micron to about 75 micron and comprising a fluorinated nanocomposite disposed over the one or more functional layers, wherein the fluorinated nanocomposite comprises a plurality of fluorinated multi-walled carbon nanotubes dispersed in one or more fluoropolymers selected from the group consisting of perfluoroalkoxycopolymer, poly(tetrafluoroethylene), fluorinated ethylene-propylene copolymer, and combinations thereof;
- feeding the media through a fuser nip such that the toner image contacts the top coat layer of the fuser member in the fuser nip;
- and
- fuse the toner image onto the media by heating the fuser nip.
