Abstract
AbstractChitosan was grafted with polyorthoethylaniline through oxidative polymerization using ammonium persulfate as oxidant, resulting in the formation of a biocomposite of chitosan-grafted-polyorthoethylaniline (CH-g-POEA). The synthesized biocomposite (CH-g-POEA) was characterized by FTIR, SEM, and TGA. Adsorption of methyl orange (MO) dye by CH-g-POEA was studied, wherein the Langmuir isotherm model with a R2 of 0.9979 and adsorption capacity of 45.7 mg/g was evaluated.

Abstract
In this paper, we present a new synthetic route to produce optically active nanofibers of poly[2-(sec-butyl) aniline] (PSBA). Optically active PSBA nanofibers were produced by in situ chemical oxidative polymerization of a racemic monomer, (±)-2-sec-buthylaniline, in the presence of 1.5 M (+)- or (-)-camphor sulfonic acid (HCSA) with a monomer concentration of 0.025 M at 0 °C. The mirror-imaged circular dichroism spectra of both PSBA/(+)HCSA and PSBA/(-)HCSA show that the two polymers are optically active enantiomers, and in this condition, the chemical oxidation of 2SBA is enantioselective polymerization. The produced polymer has a uniform nanofibrillar morphology with an average diameter of 55 nm according to scanning electron microscopy and a number average molecular weight of 4680 g/mol as determined by gel permeation chromatography.

Abstract
Electrically conductive polyorthochloroaniline/chromium nanocomposites (POC/Cr NCs) were prepared by in situ chemical oxidative polymerization of orthochloroaniline in the presence of Cr nanoparticles (Cr NPs). The load percentage of Cr nanofiller was varied in POC matrix to investigate the effect of Cr nanoparticles on the properties of the nanocomposites. The composition, structure, and morphology of POC and its composites were examined by Scanning electron microscopy, Fourier transform infrared spectroscopy, and UV–visible spectroscopic analysis. The antibacterial potential of POC and its composites was evaluated by the disc diffusion method against Escherichia coli and Bacillus subtilis. The results showed the improved antibacterial potential with the increase in the load percentage of nanofiller. The electrical conductivity of polymer and its composites was measured and correlated with the load percentage. The results showed that electrical conductivity of the composites was enhanced with the increase in load percentage of Cr nanoparticles.![]()
