Effect of metal phthalocyanines on the synthesis and physicochemical properties of polyaniline

One of the most studied conducting polymers is polyaniline (PANI) which exists in different forms depending on its level of oxidation, and its conductivity can be determined depending on the level of the obtained oxidation state. The polymer can achieve some electrical conductivity properties by means of a doping process of the protonated form known as emeraldine salt (ES). Also, PANI is a polymer that has been widely studied because of its conductive properties, ease of preparation, low cost, and high chemical stability under normal environmental conditions; however, since it possesses a low processability, it is common to dope it in order to increase its conductive properties. In this study, PANI was obtained by the oxidation polymerization method and its deposition into thin films by the spin coating method.

“…The preparation of hybrid materials based on conductive polymers and phthalocyanines is carried out using the following methods: (1) the electrocopolymerization of phthalocyanines molecules with electroactive monomers, for example, 3,4-ethylenedioxythiophene (EDOT) [6][7][8][9][10] or aniline [11]; (2) the use of phthalocyaninates with anionic substituents (carboxylic or sulfonic groups) as a charge-compensating anion in the electropolymerization of aniline [12,13], pyrrole [14,15], and EDOT [3]; (3) the chemical polymerization of EDOT in the presence of polystyrene sulfonic acid (PSSA) with copper phthalocyanine [16], poly(sodium styrene sulfonate), and transition-metal tetrasulfonated phthalocyanine as catalysts [17], and the chemical polymerization of aniline in the presence of hydrochloric acid and metal phthalocyaninates [18,19]. Another way to prepare hybrid material is the mixing of PEDOT-PSSA and copper phthalocyanine water dispersions.…”

The electrochemical polymerization of 3,4-ethylenedioxythiophene (EDOT) was performed in the presence of a water-soluble anionic copper and zinc octa(3′,5′-dicarboxyphenoxy)phthalocyaninate containing 16 ionogenic carboxylate groups. The influences of the central metal atom in the phthalocyaninate and EDOT-to-carboxylate group ratio (1:2, 1:4, and 1:6) on the course of electropolymerization were studied using electrochemical methods. It has been shown that the polymerization of EDOT in the presence of phthalocyaninates proceeds at a higher rate compared to that in the presence of a low-molecular-weight electrolyte (sodium acetate). Studies of the electronic and chemical structure using UV–Vis–NIR and Raman spectroscopies showed that the use of copper phthalocyaninate leads to a higher content of the latter in PEDOT composite films. The 1:2 EDOT-to-carboxylate group ratio was found to be optimal for a higher content of phthalocyaninate in the composite film.
