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.
