摘要:
A method of making a polymeric composition comprising a fluorocarbon-silicone interpenetrating network, comprising the steps of: a) mechanically compounding a fluorocarbon copolymer and metal oxide or hydroxide acid acceptor to form a homogenous mixture; and b) dispersing in solvent the mixture formed by step a) with a polymer selected from a curable polyfunctional poly(C(1-6) alkyl)siloxane polymer; a curable polyfunctional poly(C(1-6) alkyl)arylsiloxane polymer; and combinations thereof, and c) solution milling the dispersion of b) to form a homogeneous blend.
摘要:
A fuser member having a support metallic core and a layer of material formed over the metallic core, an intermediate layer, and an outer layer, the intermediate layer including a cross-linked poly(dialkylsiloxane); one or more multifunctional silanes; one or more amino functional silane crosslinking agents; catalyst; and optional fillers.
摘要:
A release agent donor member for a toner fixing system, the donor member includes: a base member; an optional intermediate layer; and an outermost layer of a polymeric composition containing a cured interpenetrating network or (a) fluorocarbon elastomer and (b) at least one silicone elastomer of polyfunctional poly(C.sub.(1-6) alkyl) siloxane polymer; polyfunctional poly(C.sub.(1-6) alkyl)arylsiloxane polymer; and combinations thereof; wherein a functionalist release agent is applied to the outer surface of the outermost layer; and wherein the outermost layer contains a metal oxide in an amount sufficient to interact with the functionalist release agent. The fluorocarbon elastomer can be a terpolymer of vinylideneflouride, hexafluoropropylene, and tetraflouroethylene, wherein the vinylideneflouride is present in an amount greater than 45 mole percent.
