Abstract:
A substrate assembly containing a conductive film and a fabrication method thereof are provided. The substrate assembly includes a polymer substrate, a surface treatment layer formed on the polymer substrate and a conductive film formed on the surface treatment layer, wherein the conductive film is formed by sintering a metal conductive ink and the surface treatment layer is formed from a composite material of an auxiliary filler and a polymer. The auxiliary filler in the surface treatment layer can deliver energy into the metal conductive ink for sintering the conductive metal ink.
