| Abstract
| - The polymerization to polyaniline nanofibers was carried out in an aqueous system using aniline, 1 M HCl. and ammonium peroxydisulfate (APS) with additional use of sodium hypochlorite solution as a co-oxidant. The addition of sodium hypochlorite solution was made either before or after the addition of APS. This new method always produces polyaniline nanofibers with long length. Additional advantages of this new method are discussed. The effect of aniline concentration, hypochlorite concentration, different acid use, reaction temperature, and both aniline and hypochlorite purity on morphology and electrical property of the nanofibers synthesized by this new method was investigated.
- Synthesis of polyaniline nanofibers becomes robust by co-use of sodium hypochlorite with ammonium peroxydisulfate as co-oxidant. The additional use of hypochlorite added the synthesis to be more consistent by reducing its sensistivity to variations of temperature, concentration, and dopant acid compared to the methods reported with other oxidants.
