Аннотация:Nanoobjects of interpolymer complex of polyaniline (PAn) and polysulfonic acid
have been synthesized. The matrix chemical synthesis of PAn was carried out in aqueous
solution at room temperature in the presence of poly-(2-acrylamido-2-methyl-1-propanesulfonic
acid) (PAMPSA) as a matrix. The choice of PAMPSA was determined by its good
solubility in water, perfect film-forming properties and high molecular weight (~ 2000000).
The polymerization process of aniline on PAMPSA took place at pH ~ 2 on the polymer
backbone at high rate, while aniline concentration was sufficiently low. The true solution of
PAn-PAMPSA interpolymer complex was coated on mica substrates. We have studied PAn
films surfaces using FEMTOSCAN atomic force microscope (AFM) in dependence on the
solution concentrations and the presence of strong electrolyte (HCl).
