Abstract
A straightforward ambient temperature route to the fabrication of surface silver-metallized polyimide films is described. Silver(I) trifluoromethane sulfonate and a polyimide, derived from 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride (6FDA) and an equimolar amount of 4,4'-oxydianiline (ODA) and 3,5-diaminobenzoic acid (DABA), were dissolved together in dimethylacetamide. Silver(I)-doped films were prepared at thicknesses of 25-50 microns and depleted of solvent by evaporation. The silver(I)-containing films were then treated with aqueous reducing agents, which brought forth silvered films exhibiting conductivity on the order of bulk polycrystalline silver and good specular reflectivity.
