Abstract
Syntheses of ethyl and ethoxy-substituted polyaniline complexes with polystyrenesulfonic acid were studied. The products were characterized by IR, VIS, EPR, and conductivity measurement. IR spectrum show that the structure of poly( 2-ethylaniline )- poly ( styrenesulfonic acid ) [P(2-E)-PSSA] and poly( o-phenetidine ) - poly( styrenesulfonic acid ) [ P(O-P)-PSSA ] complexes is similar to that of polyaniline. EPR and visible spectra indicate the formation of polarons. The pH value for deprotonation is higher than that of corresponding HCl salts indicate intimate interaction between polymer chains. Conductivity of the complexes is around 10 -2 S/cm. The solubility of P(2-E)-PSSA and P(O-P)-PSSA in water is 5.6 g/L and 8.0 g/L, respectively.
