Electrochemical synthesis and study of poly(2,5-diarylamino-3,6-dichlorobenzoquinone) and its composite with multiwalled carbon nanotubes

Аннотация

A procedure has been developed for electrochemical polymerization of dianiline dichlorobenzoquinone and electrosynthesis of a composite material based on poly(dianiline dichlorobenzoquinone) and multiwalled carbon nanotubes (MCNTs) in 1 M H₂SO₄. The introduction of a polymerization initiator (potassium hexachloroiridate IrCl₆²⁻ (HCI)) accelerated the growth of the electrode coating. The introduction of MCNTs led to the creation of a current-conducting framework in the composite and an increase in the mass and electrochemical capacity of the electrode coating. The electrochemical behavior of the composite is similar to that of polyaniline (PAni), but includes the redox reaction of the chloranil substituents. The charging of the double electric layer makes a significant contribution to the electrochemical capacity.
