Composite materials and methods of producing the same are provided. In some embodiments, the composite materials can comprise a polymer substrate, an intermediary material, such as a metal or oxide, mechanically attached onto the polymer substrate, and an elastomer bonded to the polymer substrate on the side of the polymer substrate comprising the intermediary materials.
