Pulse electropolymerization synthesis of PPy(DBS) nanoparticle layers

摘要: A one-step process using a pulse electropolymerization technique is used to fabricate nanoparticles of polypyrrole (PPy) with dodecyl benzene sulfonate (DBS) anions from an aqueous solution without template and any chemical additives. The morphology particles controlled by changing the duration (from 120 0.5 s), while keeping relaxation time constant at 15 s. Short pulses resulted in formation PPy(DBS) nanoparticles with average particle size about 50 nm. control ascribed growth mechanism, whereby progressive nucleation associated two-dimensional initiated each new cycle equilibrium electrolyte solution. are needed avoid nonuniform size. Sufficiently long required restore concentrations vicinity working electrode suppressing double layer. Combining short sufficiently times enables nanoparticles. proposed short-pulse meant be applied fabrication wide range nanostructured conductive polymers.
