Tuning PANI nanostructure by driving force for diverse capacitance performance†
Abstract
PANI with controllable nanostructures, i.e., helixes, nanofibers and nanoparticles, were obtained through a self-assembly process during emulsion polymerization by simply regulating the stirring. PANI helixes and nanofibers exhibit better capacitance performance than PANI nanoparticles due to higher crystallinity, regularity and conductivity of PANI in the 1D nanostructures.
