Kinetics of micelle formation and their effect on the optical and structural properties of polypyrrole nanoparticles

► Nanoparticles of polypyrrole (∼20-40 nm) synthesized using chemical method. ► Structural and optical properties studied. ► High energy absorption observed ∼5.2 eV. ► Kinetics of micelle formation discussed from thermodynamic consideration. ► Using micellar nucleation theory, growth mechanism of polymer nanoparticles proposed.
