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 degrees C.
