The stability of full-conjugated self-assembled (SA) multilayer films based on partially doped polyaniline (PANI) as a polycation and poly(o-aminobenzoic acid) (PCAN), poly(aniline-2-sulfonic acid) (PSAN) as polyanions is investigated in alkali aqueous solutions. The self-assembled PANI-PCAN films keep their stability within 24 h in 1 mol/L NaOH solution,-the PAN1-PSAN films, however, maintain the stability for 20 min in the same condition because the solubility of PSAN in alkali solutions is much higher than that of PCAN. The electrochemical properties of the SA films are determined, and the film-CdS composites formed in situ are also reported.
