Abstract:
1. A fuser member comprising a substrate, and thereover, an outer layer comprising polysilsesquioxane dispersed in a fluoroelastomer comprising polymer chains, wherein said polysilsesquioxane are present in an amount ranging from about 0.1 percent to about 30 percent by weight of total solids of the outer layer; wherein said fluoroelastomer is selected from the group consisting of (1) a class of copolymers of two of vinylidenefluoride, hexafluoropropylene and tetrafluoroethylene, (2) a class of terpolymers of vinylidenefluoride, hexafluoropropylene and tetrafluoroethylene, and (3) a class of tetrapolymers of vinylidenefluoride, hexafluoropropylene, tetrafluoroethylene and a cure site monomer; wherein said polysilsesquioxane are fixed in the fluoroelastomer by reacting the polymer chains with compounds of Formula II: wherein R wherein said outer layer comprises a polymer matrix formed of said fluoroelastomer, and wherein said polysilsesquioxane are covalently bonded to said polymer matrix via linkages formed from the hydroxyphenyl crosslinking group, and wherein R
