Abstract

Monodisperse polyaniline (PANI) nanoparticles were synthesized from an oxidative dispersion polymerization using poly(sodium 4-styrenesulfonate) as both a polymeric stabilizer and a doping agent due to its acidity. Particle size and shape of the PANT were examined via SEM, TEM and dynamic light scattering (DLS). The particles were also characterized, spectroscopically by UV-VIS, and its conductivity was determined to be between 10-1 and 100 S cm-1. The electrorheological fluids of the PANI nanoparticles were further prepared and their rheological properties were investigated using a rotational type rheometer equipped with a high voltage generator.
