[1] The production of polyaniline materials and various functional compounds contributes to their better physicochemical properties. [2][3][4][5][6][7] The literature pays special attention to P1 synthesis under organic metal complexes, namely, the monoethanolamine cobalt complex, which provided a better corrosion inhibition than that of P1.…”

Effect of Cobalt Phthalocyanine on Synthesis and Physicochemical Properties of Polyaniline

2019

View full text Add to dashboard Cite

Organic transition metal complexes are successfully used in polymerization due to their catalytic activity in oxidative reactions. Here, polyaniline was synthesized with cobalt phthalocyanine as catalysts for the aniline oxidative polymerization. The conditions for obtaining polyaniline significantly affect the final product and the introduction of the component into the reaction mixture leads to a change in the physicochemical properties of the polymer. Thus, the effect of the catalyst on the polymer chain was determined using FTIR, UV‐visible spectral methods and atomic adsorption analysis. Electrical conductivity, thermal stability, electrochemical parameters (HOMO‐LUMO, band gap), surface morphology, and fluorescence emission spectra were estimated for the polymer samples obtained. The study of synthesized polymeric materials resulted that the use of cobalt phthalocyanines in the aniline oxidative polymerization process leads to better physicochemical properties, namely electrical conductivity, band gap and fluorescence quantum yield.

“…The classical synthesis of PANI involves the polymerization of aniline in acidic aqueous medium using oxidizers like ammonium peroxodisulfate (APS), or by electrochemical means . Improved control on the morphology and hence the properties can be realized by carrying out the synthesis at interfaces; interesting mesoscopic and macroscopic patterns have been reported in the polymerization of aniline at the air‐water interface coupled with chemical reactions in the bulk aqueous phase .…”

Morphological and organizational control afforded by polymerization at the air‐water interface, and the unique structural features of poly(N‐alkylaniline)s are exploited in the fabrication of the polymer and polymer‐nanoparticle composites in micro and nanofiber (ultrathin film) forms. While ammonium peroxodisulfate as the oxidizer provides poly(N‐octadecylaniline) (PNOA), chloroauric acid leads to the nanocomposite, PNOA_Au. Experiments using relatively larger amounts of the monomer in a petri‐dish produced PNOA and PNOA_Au microfibers that could be characterized using spectroscopy, microscopy and electrical conductivity measurement. Polymerization in monolayer Langmuir films under surface pressure control in a Langmuir‐Blodgett (LB) trough, allowed the kinetics to be monitored, and ultrathin films of PNOA and PNOA_Au to be fabricated. The PNOA LB film shows nanofibers with twists, turns and helical segments, aligned parallel to the direction of monolayer compression; a computational model suggests a helical chain structure for PNOA formed at the interface. The polymer nanofibers are decorated with Au nanoparticles in the PNOA_Au film.

“…It has been used in the rock industry to create industrial construction, highway engineering and building tiles for other purposes [1]. Polyaniline (PANI) is one of the most promising conductive polymers for technological applications due to its easy synthesis, high environmental stability, huge electrical conductivity, as well as a comparatively low cost [2,3]. PANI is synthesized for specific applications like organic electronics [3], circuit component (such as varistors [4], super capacitors [3,5]), electrochemical catalysis [5,6], corrosion protection [7,8] and sensors [9].…”

Abstract-In the present study, the dielectric permittivity change of basalt (two type basalt; CM-1, KYZ-13) reinforced PANI composites were studied to determine the effects of PANI additivities (10.0, 25.0, 50.0 wt.%) at several frequencies from 100 Hz to 17.5 MHz by a dielectric spectroscopy method at the room temperature and artificial neural networks (ANNs) simulation. Also, the dielectric permittivity at 30.0 wt.% of PANI additivity was obtained by ANNs without experimental process. That process, a significant predictive instrument was produced which allows optimization of dielectric properties for numerous composites without substantial experimentation. It has been observed that PANI additivities decreased to dielectric constant of composites at low frequencies. Furthermore, the ANNs method have satisfactory accuracy for prediction of dielectric parameters.
