摘要

Acid doped Polyaniline(PANI)due to their increased electrical conductivity,are considered to be the most promising conducting filler materials.Hence,the present study,reports the synthesis of the PANI followed by acid doping,electrical conductivity and dielectric properties measurements of H2SO4;HCl and(Conc.HCl+NaNO2mixture)doped PANI.In order to know the effect of acetone washing on the electrical properties of acid doped PANI samples,the electrical properties of the non-acetone washed acid doped PANI samples are compared with that of their acetone washed counterparts.The PANI salt was prepared by conventional route using aniline hydrochloride and ammonium persulphate as an oxidant.PANI salt was subjected to 0.5M NaOH to form PANI base,which was further doped separately with H2SO4;HCl and(Conc.HCl+NaNO2mixture)respectively followed by acetone washing.A comparative electrical conductivity study between the acetone washed and unwashed PANI salt and H2SO4,HCl and Conc.HCl+NaNO2 mixture doped PANI were characterized by dielectric and impedance study.
