Fuser manufacture and article
According to an embodiment a method of making a fuser member is described. The method includes, obtaining a silicone layer disposed on a substrate and coating a primer composition including an aqueous dispersion of a fluorelastomer and a curing agent on the silicone layer. A topcoat composition is coated on the primer composition which includes a fluoroplastic dispersion. The primer composition and the topcoat composition are heated to form the fuser member.
1. A fuser member comprising:
a substrate;
a silicone layer disposed on the substrate;
a primer layer disposed on the silicone layer, the primer layer comprising a crosslinked amino-silane and fluoroelastomer, and conductive fillers wherein the primer layer has a thickness of from about 1 μm to about 10 μm, and wherein the primer layer has a surface resistivity of less than 10 5 ohms/square; and
an outer layer disposed on the primer layer wherein the outer layer comprises a fluoroplastic.
2. The fuser member of claim 1 wherein the outer layer has a thickness of from about 20 μm to about 100 μm.
3. The fuser member of claim 1 wherein the conductive fillers are selected from the group consisting of single-walled carbon nanotubes, double-walled carbon nanotubes, multi-walled carbon nanotubes, carbon black, acetylene black, graphite, graphene, metal, metal oxide, doped metal oxides metal carbide and polyanaline.
4. The fuser member of claim 3 wherein the fuser member has a surface resistivity of less that about 10 9 ohms/square.
5. A fuser member comprising:
a substrate;
a silicone layer disposed on the substrate;
a dual-primer layer comprising a first primer layer disposed on the silicone layer comprising a crosslinked product of amino-silane and fluoroelastomer, and a second primer layer disposed on the first primer layer comprising a conductive filler and a fluoropolymer wherein the dual-primer layer has a thickness of from about 1 μm to about 10 μm, wherein the primer layer has a surface resistivity of less than 10 5 ohms/square; and
an outer layer disposed on the second primer layer wherein the outer layer comprises a fluoroplastic.
6. The fuser member of claim 5 wherein the conductive filler is selected from the group consisting of carbon nanotubes, carbon black, acetylene black, graphite, graphene, metal, metal oxide, doped metal oxides metal carbide and polyanaline.
