摘要: Novel poly(pyrrole-co-aniline-2-sulfonic acid) (PPYAS) nanoparticles were prepared via chemical oxidative polymerization of pyrrole and aniline-2-sulfonic acid in different aqueous solutions without any external additives. The morphology, structure electroconductivity the HCl-doped particles studied by changing molar ratio oxidant monomers, solvent for polymerization. It was found that yield, mean diameter electrical conductivity resulting varied strongly with components. exhibit a minimum around 62 nm, good self-stability because introduction sulfo groups into chains copolymer. preparation affords yield up to 85%, copolymer salts possess an between 0.68 0.2 S/cm, depending on fraction anilinesulfonic acid.
