Synthesis and Characterization of Polyaniline Nanofibres by Rapid Liquid-Liquid Interfacial Polymerization Method

Abstract

Inherently conducting polymer polyaniline (Pani) has been synthesized by a novel interfacial polymerization technique using trichloroethane as organic media. Ammonium peroxydisulphate was used as an oxidizing agent dissolved in aqueous media. The synthesized polymer was subjected to the physico-chemical characterization by UV-Vis and FT-IR Spectroscopy and Scanning Electron Microscopy. From the SEM Micrographs it was observed that interfacial polymerization offers the fibrillar type of morphology having 200 nm sized fibers. Thermal properties of the synthesized polyaniline nanofibres were evaluated by thermogravimetric analysis. Conductivity of the polymer was measured by four-probe conductivity measurement technique and found to be ~ 0.1 S/cm.
