Abstract
A member for a fuser assembly of a printer. The member may include a support body and a composite coating disposed on an outer surface of the support body. The composite coating may include a fluororesin and a nanocarbon material dispersed within the fluororesin. The nanocarbon material may be present in a higher concentration proximate the support body and a lower concentration proximate an outer surface of the composite coating. The lower concentration may be less than or equal to about 2 wt % of the nanocarbon material.
Claims20
A member for a fuser assembly of a printer, comprising:
- a support body;
- and
- a composite coating disposed on an outer surface of the support body, the composite coating comprising a fluororesin and a nanocarbon material dispersed within the fluororesin, wherein the nanocarbon material is present in a higher concentration proximate the support body and a lower concentration proximate an outer surface of the composite coating, and wherein the lower concentration comprises less than or equal to about 2 wt % of the nanocarbon material.
A fuser assembly of a printer, comprising:
- a member having a support body;
- and
- a composite coating disposed on an outer surface of the support body, the composite coating comprising:
- a first layer comprising a first fluororesin and a first nanocarbon material present in an amount from about 2 wt % to about 50 wt %, wherein the first layer has a thickness from about 10 μm to about 50 μm;
- and
- a second layer at least partially disposed on the first layer, the second layer comprising a second fluororesin and a second nanocarbon material, wherein the second nanocarbon material is present in the second layer in an amount less than or equal to about 2 wt %, wherein the second layer has a thickness less than or equal to about 10 μm, and wherein the first nanocarbon material, the second nanocarbon material, or both comprises carbon nanotubes, graphene, or a combination thereof.
A method of producing a fuser member, comprising:
- applying a first layer of a composite coating onto an outer surface of a fuser member substrate, wherein the first layer of the composite coating comprises a first fluororesin, a first nanocarbon material, a first dispersing agent, and a first solvent;
- drying the first layer of the composite coating at least partially;
- applying a second layer of the composite coating onto an outer surface of the first layer, wherein the second layer comprises a second fluororesin, a second nanocarbon material, a second dispersing agent, and a second solvent;
- and
- heating the fuser member substrate, the first layer, and the second layer to a temperature ranging from about 285° C. to about 380° C. to form a dual-layer composite coating on the fuser member substrate.
