Highly reflective and conductive silver surfaces on flexible polyimide films have been achieved by a novel single‐stage self‐metallizing procedure that utilizes similar chemistry to that involved in CVD. The film is cast as a silver( I )‐doped poly(amic acid) solution. Thermal curing leads to cycloimidization of the polyimide precursor with concomitant silver( I ) reduction. The result is a reflective and conductive surface approaching that of the native metal, while the film retains the essential mechanical and thermal characteristics of the parent film.
