Abstract
A series of tin-containing polyimide films derived from either 3,3′,4,4′-benzophenone tetracarboxylic acid dianhydride or pyromellitic dianhydride and 4,4′-oxydianiline have been synthesized and their electrical properties examined. Highest quality materials (i.e. homogeneous, smooth surface, flexible) with the best electrical properties were doped with either SnC12·2H2O or (n-Bu)2SnC12. In all cases, extensive reactivity of the tin dopant with water, air or polyamic acid during imidization is observed. Lowered electrical surface resistivities appear to be correlatable with the presence of surface tin oxide on the film surface.
