Abstract

Needle-like polyanilines (PANi) were prepared at 15 °C by emulsion polymerization and their conductivities were obtained up to 3 S/cm according to the addition rate of ammonium peroxysulfate (APS) aqueous solutions with reaction conditions of 0.4 to 0.5 APS/aniline ratios and 0.4 to 0.5 M aniline concentrations. Needle-like complexes doped with p-toluenesulfonic acid (pTSA) were prepared with the oxidant solution added so slowly as to be for 3 to 3.6 hours. The high reaction temperatures ranging from 5 to 15 °C was the second condition to have needle-like anilinium complexes polymerized without their breaking during polymerization. A filler shape is one of the most important parameters influencing a percolation concentration of conductive fillers dispersed in a non-conductive matrix. Needle-like polyanilines could be potentially used as conductive fillers to show electromagnetic interference and radar absorption effects.
