Modulating the properties of carboxymethyl chitosan/polyethylene oxide nanocomposites with aluminium oxy hydroxide: A comprehensive study.

This study explores the eco-friendly synthesis of carboxymethyl chitosan/polyethylene oxide/γ-aluminium oxyhydroxide (CMCS/PEO/γ-AlOOH) nanocomposite films through a sustainable, green preparation method. The CMCS/PEO/γ-AlOOH nanocomposites were characterized through X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) to analyze their structural and morphological properties. The emergence of distinct peaks of γ-AlOOH in XRD and FTIR spectra indicated the strong interaction between γ-AlOOH and the blend.

Eco-friendly synthesis, characterization, and properties of copper oxide nanoparticles in cashew gum/polypyrrole blend for energy storage applications.

Conducting biopolymer blend nanocomposites of cashew gum (CG) and polypyrrole (PPy), with varying concentrations of copper oxide (CuO) nanoparticles were synthesized through an in-situ polymerization method using water as a sustainable solvent. The formation of blend nanocomposites was characterized using UV-visible (UV-vis) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). UV spectroscopy revealed a significant reduction in absorption intensity with the addition of CuO, indicating enhanced optical properties.

Development of High-Performance Polyindole/Silicon Carbide Nanocomposites for Optoelectrical and Sensing Applications.

In this study, silicon carbide (SiC)-reinforced polyindole (PIn) nanocomposites were prepared by a simple in situ polymerization method. The successful reinforcement of the nanofiller within the host matrix was characterized using different analytical techniques. The chemical bonding of SiC in the polymer was identified by the characteristic peak around 800 cm using Fourier transform infrared spectroscopy (FT-IR).

Copper alumina @ poly (aniline--indole) nanocomposites: synthesis, characterization, electrical properties and gas sensing applications.

Poly(aniline-co-indole)/copper alumina (PANI--PIN/Cu-AlO) with excellent AC conductivity, dielectric properties, and ammonia gas detecting capabilities were synthesised chemical oxidative polymerization. The presence of Cu-O bonding vibrations and shift of some characteristic peaks in the Fourier transform infrared spectroscopy (FT-IR) revealed the successful encapsulation of Cu-AlO nanoparticles in the copolymer. The XRD studies showed the crystalline peaks of Cu-AlO in the PANI--PIN nanocomposites.
