Title

Photolithographically Patterned Covalently Bonded Polythiophene Films Using in Tandem Sol-gel, Surface Initiated Free Radical and Redox Polymerization Methods

Abstract

Mechanically strong crosslinked conducting polymer films covalently bonded to substrate open the room to more robust applications. A bifunctional monomer, 3,4-bis(vinyloxy)thiophene (BVOT), which can be polymerized both by radical as well as by redox chemistry was synthesized and was utilized in the fabrication of lithographic patterns of conducting polymer films via a sol-gel method. The judicious use of several chemistries yield polythiophene covalently bonded to substrate showing superior adhesion and increased mechanical strength over their physically bonded counterparts. The films were characterized electrically and mechanically. The conducting copolymer films showed electrical conductivity of 65 S m-1with 200 nm thickness.
