  • Use of amorphous carbon to promote adhesion between electroactive polymer films and conductive substrates
    Patent number: 5100523
    Abstract: An interposed layer of amorphous carbon promotes the adhesion between conductive substrates and electrochemically deposited polymers. Such a carbon layer may be deposited directly onto the conductive substrate by conventional methods such as, for example, chemical vapor deposition. The subsequently applied electrochemically deposited polymer adheres more tenaciously to the amorphous carbon coating than if it had been electrodeposited directly onto the conductive substrate.
