Objective
The aim of this project is to increase our knowledge of the interface properties and the deposition processes, with or without external current, of a new type of electrical contact. Instead of considering the traditional and largely explored field of purely metallic conductors, the innovative aspect of the project is to propose the utilization of an organic polymer film. The Polymer selected normally is an insulator, but in this case it behaves as a metal due to the particular conditions of polymerisation and an appropriate post- treatment. The economic benefit of this project will accrue in the replacement of gold, used in the protection of contacts, by a cheaper material, or to limit its utilisation by improving the properties of contact (contact resistance, tribology, resistance against corrosion and vibration, and constancy in aspect).
The project concerned the formation of a polymeric film, grafted onto a metallic cathode, through electropolymerisation in nonaqueous media. From the industrial point of view, the aim was to develop a completely original type of coating, perhaps able to reduce, or even to suppress, the classical gold coating upon electrical contacts for connectors. The projectresulted in development of an electrically conducting polymeric coating (based on peroxyacylnitrate (PAN)) which can be applied to nickel plated metal supports.
Studies have been carried out on acrylonitrile electropolymerization on to a nickel cathode surface. These studies increased knowledge concerning the behaviour of the monomer molecule during its approach to the cathode and the formation of the first radical. The structure of the early polymer layer, the growth mechanism and the global structure of the final polymer film were also studied.
Comparisons with metals other than nickel as the cathode and with monomers other than acrylonitride have been made. These proved the possibility of extending the process to many other cases and they also contributed to the comprehension of basic features.
In order to improve their electrical conductivity some films were submitted to different posttreatments (moderate heating, ultraviolet radiation). In each case the chemical structure of the polymer is severely affected, through oxidation, hydrolysis and/or cyclization. From the application point of view the film electrical behaviour changes from insulating to conducting. Friction behaviour and resistance to corrosion were also improved.
THE EMPHASIS IN THIS PROJECT IS TO INCREASE THE KNOWLEDGE ON THE INTERFACE PROPERTIES AND THE DEPOSITION PROCESSES, WITH OR WITHOUT EXTERNAL CURRENTS, OF A NEW TYPE OF ELECTRICAL CONTACT.
INSTEAD OF CONSIDERING THE TRADITIONAL AND LARGELY EXPLORED FIELD OF PURELY METALLIC CONDUCTORS, THE INNOVATIVE ASPECT OF THE PROJECT IS TO PROPOSE THE UTILIZATION OF AN ORGANIC POLYMER FILM. THE POLYMER SELECTED NORMALLY IS AN INSULATOR, BUT IN THIS CASE IT BEHAVES AS A METAL DUE TO THE PARTICULAR CONDITIONS OF POLYMERISATION AND AN APPROPRIATE POST-TREATMENT.
