Fabrication of Honeycomb-Patterned Polyaniline Composite Films Containing Cellulose Triacetate With High Conductivity and Mechanical Stability

摘要

Polyaniline (PANI) biocomposites were prepared via in situ polymerization of aniline monomer with cellulose triacetate (CTA) and by using ammonium persulfate as an initiator in an aqueous solvent. The composites exhibited high solubility in organic solvents due to the incorporated CTA component, and enabled the fabrication of honeycomb-patterned thin films by casting the PANI composite solutions under humid conditions. The honeycomb-patterned PANI-CTA composite films showed a high conductivity corresponding to about 1.5 S/cm, good mechanical stability, and high flexibility. The composites have a potential advantage comparing to pure PANI because of biodegradability and high solubility due to included CTA. These composite films can usefully be applied in the field of bio-nanotechnology and medicine including micro-structured electrode surfaces, filters for cell sorting, and bio-interfaces and so on.
