Recently, there have been many reports of electrically conductive natural polymers which can be applied to a display industry. Cellulose can be an alternative matrix to deal with a low thermal stability of plastics. In this study, polyaniline on cellulose surface was produced readily by interfacial polymerization. Setting up two phases with organic solvents and water, the polymerization in the interface and aqueous phase was observed. Bacterial cellulose was introduced between phases. To compensate the brittleness of conductive polymer, polyvinyl alcohol was used in an aqueous phase to improve the mechanical properties. To control the crystallinity of polyaniline nanofibers, we investigated the results from trying several different ratios of oxidants to monomer and reaction time. For measurements, SEM, TGA, FT-IR, UV-visible spectroscopy and 4-point probe were used to check its surface morphology, thermal stability, chemical characterization, transmittance and conductivity. |
