Spectral and thermal studies on polyaniline-epoxy novolac resin composite materials

Abstract

Polyaniline–epoxy novolac resin composite materials (PANI–RESIN) were prepared by emulsion polymerization technique and characterized by infrared and electronic absorption spectra, conductivity, particle size, and thermogravimetric and differential scanning calorimetric analysis. The conductivity of PANI–RESIN samples decreased with the addition of the RESIN as 0.1, 0.02, and 0.04 S/cm for 25, 50, and 75% addition of the RESIN, respectively. TGA thermograms of PANI–RESIN samples are more or less similar to those of polyaniline salts (PANI), which were stable up to 225°C. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 74: 3507–3512, 1999
