Abstract :

The organic conducting polymers also called as “synthetic metals” have received considerable attraction among chemists. Polyaniline holds a special position amongst conducting polymers due to its low cost, easy synthesis and processibility. Its conductivity and chemical properties can be modified by doping with suitable dopants. The present paper deals with the synthesis of polyaniline by chemical oxidative polymerization using picric acid as the dopant. Characterisation of Polyaniline picrate (PANIPI) is carried out using UV–Visible, FT–IR, 1HNMR, mass and elemental analysis. The electrical conductivity of pressed pellet is 1.5 Scm–1. The effect of thermal treatment on PANIPI is investigated using four probe conductivity and TGA technique. SEM, PXRD and particle size analysis have been used to reveal its size and structural morphology
