Poly ortho aminophenol/TiO2 nanocomposite: Electrosynthesis and characterization

► Ultrasonic technique was employed to prepare composite shell-core particles. ► The aggregates of nanocrystalline TiO2 are broken under ultrasonic irradiation. ► Composites have more active sites and larger specific capacitance. ► The surfactant molecules have a stabilizing effect on the composite formation.
