Abstract : A technique is described for attaching thin, conformal, pin-hole free electrically insulating polyethylene films to flat gold surfaces (previously modified by adsorption of a monolayer of an organic disulfide) by plasma polymerization. These polyethylene films are tough enough to support the attachment of gold electrodes. The adhesion of plasma polymerized polyethylene (PPE) thin films to a gold surface can be dramatically improved by coupling the synthesis of the PPE thin film with the prior assembly of an organic monolayer chemisorbed to the metal surface. These thin film assemblies have good physical characteristics and are stable to the ambient environment for long intervals. This method should be applicable to other systems with appropriate modifications.
