Abstract
The studies of polyaniline (PANI) and other conducting polymers have shown that they possess semiconducting-properties. PANI is one of the conductive polymers used as a battery electrode, corrosion inhibitor, and sensor. The study aims to investigate the effect of hydrochloric acid dope to PANI. Polyaniline was synthesised by the oxidation of aniline with ammonium peroxidisulphate (APS) as an oxidant by the interfacial method in an immiscible organic/aqueous biphasic system, with hydrochloric acid as a dopant. The result showed that, PANI has conductivities in the range of 3.00.10-2-7.00.10-2 S.cm-1. The morphology and molecular structure of PANI were characterised by scanning electron microscopy (SEM), and FTIR respectively.
