摘要: A new stable miniemulsion of aniline was prepared using sodium dodecyl sulphate (SDS) as the surfactant and cetyl alcohol cosurfactant. The oxidative polymerization reaction initiated by ammonium peroxy disulphate (APS). At end polyaniline (PAni) formed treated with stannous chloride (SnCl2) finally doped p-toluene sulphonic acid (PTSA). monomer to oxidant polymer dopant mole ratio were optimized. Maximum conductivity is obtained ratio1:1 1:0.5. There a decrease in particle size increase solubility process. Dramatic due treatment SnCl2. Part pernigraniline (PNB) form PAni reduced SnCl2 emeraldine base (EB) having higher conductivity. Plausible reduction mechanism proposed. conduction explained EPR measurement. reason for difference different forms help polaron formation hole theory.
