TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The filler particles are carbon black, iron oxide, copper oxide, metallic flakes or nickel coated graphite. Preferred Process: The first nonconductive layer and the second layer are modified by a charged particle process. The charged particle process is corona discharge or plasma treatment. The corona treatment is conducted in the presence of a solvent atmosphere, where the solvent atmosphere is a ketone.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: In the optoelectric device, the multilayer film is a backsheet to the optoelectric component.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The multilayer film further comprises a third nonconductive layer such that the first and third nonconductive layers enclose the second layer. The first nonconductive layer, the polymeric matrix material and the third nonconductive layer is a polyolefin and its copolymers, epoxy resin, a cyanate ester, a polyester, a polyamide, a polycarbonate, a fluoropolymer, a polyimide, a polyacrylic compound, a polymethacrylic compound, a thermoplastic olefin, ethylene vinyl alcohol, ethylene vinyl acetate, ethylene methacrylate, thermoplastic urethane, a thermoplastic silicone, an ionomer, ethyl butyl acrylate, polyvinyl butyral and/or an ethylene propylene diene M-class rubber. The fluoropolymer is: polytetrafluoroethylene, polyvinylidenes fluoride, polychlorotrifluoroethylene, polyvinylfluoride, tetrafluoroethylene/hexafluoropropylene/ethylene copolymer, chlorotrifluoroethylene/vinylidenefluoride copolymer, chlorotrifluoroethylene/hexafluoropropylene, chlorotrifluoroethylene/ethylene copolymers, ethylene/trifluoroethylene copolymers, ethylene/tetrafluoroethylene copolymers and/or fluorinated ethylene/propylene copolymers; or an ethylene tetrafluoroethylene or a fluorinated ethylene propylene. Preferred Process: The process (Ia) further comprises: contacting the charged particle filled layer with a second casting composition, where the second casting composition comprises a carrier and a nonconductive polymer, hence providing the multilayer film; contacting the charged particle filled layer with a third casting composition, where the third casting composition comprises a carrier and a nonconductive polymer, hence providing a 3 layer multilayer film where the charged particle layer is in between the first and third nonconductive layers; and subjecting a nonconductive layer to a charged particle process. The process (Ib) further comprises: coextruding a nonconductive third layer adjacent to the charged particle layer; and subjecting a nonconductive layer to a charged particle process. EXAMPLE - Carbon black concentrate was mixed with EP 521 (RTM: Ethylene tetrafluoroethylene copolymer). The mixture was then charged into a hopper feeding a 24:1 single screw extruder fitted with a screw having mixing elements and feeding channel B of an ABC feedblock. Unfilled EP 521 (RTM: Ethylene tetrafluoroethylene copolymer) resin was charged into two separate hoppers, each connected to a 24:1 single screw extruder feeding the A and C channel of an ABC feedblock. The feedblock was further connected to a 8'' coat hanger type flat film die. Extruder heaters corresponding to the compression zone, clamps, melt pipes and die temperatures were set at 560 degrees F. Extruder screw speeds were varied to obtain the multilayer film.
