FUSER MEMBER WITH FLUOROPOLYMER OUTER LAYER

A fuser member comprising: a substrate comprising an outer substrate surface; and an outer layer comprising compatible first and second fluorothermoplastics disposed over the outer substrate surface, wherein the first fluorothermoplastic is a crosslinked polymer and the second fluorothermoplastic is a linear polymer and wherein the compatible first and second fluorothermoplastics form a semi-interpenetrating polymer network (SIPN). The SIPN provides a relatively compliant layer in comparison to use of the crosslinked polymer alone, and avoids the need for sintering of a layer formed from the linear polymer alone. The SIPN may be formed from an aqueous coated composition of polyperfluoroalkoxy-tetrafluoroethylene (PFA) and THV Fluoroplastics (FLC) polymers along with a soluble organic primary amine for crosslinking the THV Fluoroplastics (FLC).
