The effect of the natural polymer gum Arabic on the synthesis of aqueous dispersible PEDOT composites

In this communication we show for the first time a straightforward methodology to synthesize water dispersible poly(3,4-ethylendioxythiophene) (PEDOT) using gum Arabic as a “green” stabilizer. The materials were characterized by UV–vis, Raman and Scanning Electron Microscopy. The formation of PEDOT/GA composites was followed by kinetics experiments where it was possible to correlate the rate constant values with the proportion of GA in the synthetic solution and the obtained morphologies.
