Characterization of Poly(3-Methylthiophene)-like Films Produced by Plasma Polymerization

Abstract

Polymers are widely used in a great number of applications because of their many advantages. For applications requiring optical and conductive properties, the choice of a suitable polymer is limited to polymers with a conjugated chemical structure such as polyacetylene, polypyrrole, and polythiophene. Very thin film of polythiophene can be deposited by electrochemical procedures and plasma polymerization. A plasma consists of a variety of reactive species (electrons, ions, radicals, etc.) and therefore many different reactions can occur. The aim of this study is to produce poly(3-methylthiophene) using the plasma technology in pulsed wave. The influence of RF power on the film properties will be evaluated.
