A novel electrochemically synthesized biodegradable thin film of polypyrrole-polyethyleneglycol-polylactic acid nanoparticles

Nanoparticles having reactive pyrrole residues were prepared from poly(1-ethoxyethylglycidyl ether)-block-poly(l,l-lactide) block copolymer. The nanoparticles were electropolymerized in aqueous media through the oxidation of the pyrrole residue and in the presence of pyrrole to form a nanocomposite thin film. The novel synthesis of these pyrrole-functionalized nanoparticles is described and the electrochemical deposition of the corresponding coating is characterized using electrochemistry, SEM and EDX.
