Before conducting polymers can be employed in many applications, some of the intrinsic properties of these materials need to be better understood. An overview of the research and development of conducting polymers being undertaken at UTS is presented. Because conducting polymers are difficult to process once fabricated, an understanding of synthesis parameters and the use of synthesis techniques to produce conducting polymer films with desired properties is of the upmost importance. Descriptions of the galvanostatic and potentiostatic techniques employed to produce polyheterocyclics are presented. Thermal properties such as thermal diffusivity, thermal conductivity and specific heat are being investigated. Preliminary results reveal that the thermal diffusivity of polypyrrole is higher than that achieved with traditional polymers. The nature of contacts and junctions with polypyrrole and poly(3-methylthiophene) are discussed. High work function metals form ohmic junctions with polypyrrole while aluminium forms a Schottky barrier with poly(3-methylthiophene). Microwave studies on polypyrrole films reveal that the microwave transmission and reflection are dependent upon the doping level of the film. Applications of the conducting polymers in data security modules and for light weight electrically conducting wires are also illustrated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
