New semiconductor core-shell based on nano-rods core materials

ABSTRACT

The present work describes a remarkable synthetic interest of semiconducting core-shell nanocomposites (CSNCs) contained aluminum oxide. Al₂O₃@terpoly(aniline, anthranilic acid, and o-phenylenediamine) (Al₂O₃/PANI-AA-o-PDA) CSNCs were fabricated by the fivefold molar ratio of the appropriate moieties with various quantities of γ-Al₂O₃ by oxidative polymerization. The formation of the Al₂O₃/PANI-AA-o-PDA CSNCs was confirmed by spectral characteristics. The feature of CSNCs is core-shell nano-rods structure with sizes 19–39 nm. The recorded σ_dc is 8.8 × 10⁻⁹-4.8 × 10⁻⁸ Ω⁻¹ m⁻¹ being in the range of semiconductor materials at room temperature and increases with increasing temperature. The newly fabricated materials were investigated as antimicrobial agents. The setup presents a facile, cheap, novel and beneficial methodology to develop novel CSNCs acquiring the required numerous functionality.

Prime Novelty Statement

The current study describes the remarkable interest in the evolution and production of conducting core-shell nanorod composites composed of nanosized aluminum oxide and aniline, anthranilic acid and o-phenylenediamine terpolymer. These core-shell nanorod composites (Al₂O₃@PANI-AA-o-PDA) were chemically synthesized in a molar ratio of 1:1:0.5 of the particular monomers and several weights of nano γ-Al₂O₃ via oxidative terpolymerization. The construction of the Al₂O₃@PANI-AA-o-PDA core-shell nanocomposites was ascertained by spectral characteristics. A reasonable thermal behavior for the original terpolymer and Al₂O₃@PANI-o-PDA core-shell nanocomposites was investigated. The bare PANI-AA-o-PDA terpolymer was thermally less stable than Al₂O₃@PANI-AA-o-PDA nanocomposites. The core-shell feature of the nanocomposites was examined to have core-shell nanorods structure with sizes 19–39 nm. The recorded σ_dc is 8.8 × 10⁻⁹-4.8×10⁻⁸ Ω⁻¹ m⁻¹ being in the range of semiconductor materials at room temperature and increases with increasing temperature. The newly fabricated materials were investigated as antimicrobial agents. The setup presents a facile, cheap, novel and beneficial methodology for developing new core-shell nanocomposites acquiring the requested various functionality.
