The effect of Ce3+ cations on polyaniline morphology and electric properties

Polyaniline (PANI) is synthesized in the potentiostatic pulse mode from an electrolyte containing Ce₂(SO₄)₃. Cations Ce³⁺ are incorporated into the polymer composition during PANI redox transformations. It is shown that PANI in its conducting and dielectric forms contains different amounts of Ce³⁺ cations. Starting with the beginning of polymerization, the Ce³⁺ cations actively form the special polymer morphology as demonstrated by SEM images. The chief consequence of the formation of so well-developed uniform nanostructure is that the latter allows the dopant anions, cations, and protons to easily enter and leave it. This, in turn, results in the high electrochemical activity of this polymer and enhances the conductivity of PANI samples doped with Ce³⁺ cations as compared with those doped with only protons.     

Synthesis and electrochemical properties of nanocomposites containing poly(3,6-bis(phenylamino)-2,5-dichlorobenzoquinone and multiwalled carbon nanotubes

The method of synthesizing nanocomposites based on multiwalled carbon nanotubes and a new polymer poly(3,6-bis(phenylamino)-2,5-dichlorobenzoquinone) containing polyaniline chains with electroactive substituents in the N-position is developed, and the electrochemical properties of the composites are studied. The in situ oxidative polymerization of N-substituted aniline performed in the presence of multiwalled carbon nanotubes makes it possible to design an organized, effective structure of the conducting composite material with enhanced electrochemical capacity and stable capacity parameters during long cycling in protic (1 mol/L H₂SO₄) and aprotic (1 mol/L LiClO₄ in propylene carbonate) electrolytes.
