Studies on Chemically Synthesized Doped Poly(o-Anisidine) and Copoly{aniline-(O-Anisidine)}

Abstract

Substituted polyaniline poly(o-anisidine) and copoly{aniline-(o-anisidine)} were synthesized by the oxidative chemical polymerization method. Sulfuric acid was used as the dopant during the polymerization process. Synthesized polymers were subjected to the spectroscopic, X-ray and thermal analysis. Formation of different oxidation states of the polymer were confirmed by the spectroscopic (UV-VIS and FTIR) analysis. Polymers reveal polycrystalline nature and orthorhombic crystal structure. Three step decomposition patterns similar to that of polyaniline are observed in the thermogram. The conductivity is found to be higher in copoly{aniline-(o-anisidine)} than poly(o-anisidine). Increase in conductivity with increasing temperature was observed in both of the polymers.

Nonlinear optical measurements of conducting copolymers of aniline under CW laser excitation

“…A unique shoulder is observed in all the copolymers at 405, 415, 440 nm and 402, 412, 405 nm which is due to polaron-p transition [18]. The observed absorption bands are in well agreement with the reported literatures [18][19][20][21][22][23].…”

Continuous wave laser induced third-order nonlinear optical properties of conducting polymers

“…UV‐VIS spectroscopy is a powerful tool for the elucidation of the interactions between the solvent, the dopant and the polymer chains . Figs.…”

Application of Polyaniline and Polyaniline/Multiwalled Carbon Nanotubes‐Coated Fibers for Analysis of Ecstasy

“…Electrodeposition of polymers is controllable by variation of some parameters, such as applied potential, monomer concentration, substituted monomers, and changing electrolyte solution [7,8]. Among the polymers, composites of polyaniline (PANI) have attracted enormous interest due to their unique properties [9][10][11][12][13][14]. For instance, Mottaghitalab et al [15] reported that PANI/CNTs composites exhibited improved mechanical strength and conductivity.…”
