A series of polyimide films containing pyridine coordinating groups doped with cobalt or nickel ions has been examined. Using 3,3′,4,4′-benzophenonetetracarboxylic acid dianhydride, films were prepared in combination with 4,4′-oxydianiline, 4,4′-dianiline sulfide, 3,3′-bis(aminopyridine)sulfide and 2,2′dioxyphenelenebis(5,5′-aminopyridine). Room temperature volume resistivities have been found to decrease slightly with sulfur and pyridine containing diamines relative to diamines which do not contain these functionalities. Doping with cobalt and nickel additives results in further lowering of room temperature volume resistivity. Preliminary temperature profiling experiments have shown that volume resistivity decreases as Tg is approached.
