Polyaniline nanoparticles with sizes of 20–40nm were prepared by the pulsed sonoelectrochemical method. These nanoparticles are characterized by IR, UV–vis, HRSEM and TEM analysis. IR and UV–vis confirm the formation of polyaniline nanostructures. The capacitance of these materials was studied by cyclic voltammetry in 1M H 2 SO 4 . The PANI nanoparticles prepared at 1V show a higher...
We report on a simple and novel sonochemical method for the preparation of polyaniline (PANI), as well as its composite, with Au nanoparticles. This technique utilizes ultrasound radiation as an energy source to facilitate the reaction by reducing the reaction time, as well as significantly increasing the yield. The tremendous increase in the reaction rates is explained on the basis of the intensive...
