Summary: Silvered polyimide films have been fabricated by direct ion exchange of a damp‐dry poly(amic acid) film with an aqueous silver solution such as silver nitrate. Thermal curing of the silver( I )‐containing films under tension leads to cycloimidization of the poly(amic acid) into polyimide with a concomitant silver( I ) reduction and aggregation at both film sides to give reflective and conductive double‐surface‐silvered polyimide films. The metallized films retain the essential properties of the parent polyimide.Surface morphology of the prepared double‐surface‐silvered polyimide films.
