Flexible PEDOT-nanocellulose composites produced by in situ oxidative polymerization for passive components in frequency filters

Conducting undoped poly(3,4- ethylenedioxythiophene) (PEDOT)-coated bacterial nanocellulose membranes were prepared through in situ oxidative polymerization of 3,4-ethylenedioxythiophene (EDOT) on the surface of the nanocellulose fibers using Iron (III) p-toluenesulfonate as an oxidant agent. The ef...

Summary:Conducting undoped poly(3,4- ethylenedioxythiophene) (PEDOT)-coated bacterial nanocellulose membranes were prepared through in situ oxidative polymerization of 3,4-ethylenedioxythiophene (EDOT) on the surface of the nanocellulose fibers using Iron (III) p-toluenesulfonate as an oxidant agent. The effect of polymerization conditions (i.e. reaction time and EDOT:oxidant molar ratio) on electrical conductivity, morphology, thermal stability and mechanical properties of the nanocomposites was investigated. High-quality and flexible PEDOT-nanocellulose membranes with an electrical conductivity as high as 1.5 S cm −1 were obtained. The electrical conductivity of nanocomposite membranes increased with increasing the monomer concentration and reaction time due to the formation of a continuous PEDOT layer that completely coated the surface of the nanofibers. The elongation at break of the membranes increased significantly from 3 to 5 days of reaction. The flexible membranes were applied as passive elements in frequency filters. The results revealed a potential use of such class of composites for flexible organic electronics.
