Paper Abstract

In this paper we investigate the electrical properties of DNA-PEDOT blends, with particular interest as semiconducting materials in thin film based Field Effect Transistors (FET) applications. We report the template polymerization of poly(3,4-ethylenedioxythiophene) (PEDOT) using a biomacromolecule, DNA, as the polyelectrolyte. The obtained biocomposite stability is very dependent on the type of oxidant used in the chemical synthesis route. The resultant polymer system is water processable and undergoes the same redox processes as PEDOT alone. Films with thicknesses of 0.5 to 1 microns were drop cast from water based solution using different ratios EDOT to DNA.
