New semiconducting core-shell nanocomposites

The present work describes a remarkable synthetic interest of semiconducting
core-shell nanocomposites (CSNCs) contained aluminum
oxide. Al2O3@poly(aniline -co- o-phenylenediamine) (Al2O3@PANI-o-
PDA) CSNCs were fabricated by fivefold molar ratio of the appropriate
moieties with various quantities of γ-Al2O3 by oxidative polymerization.
The formation of the Al2O3@PANI-o-PDA CSNCs was confirmed by
spectral characteristics. The nanocomposite core-shell feature was
found cores thickness 38 nm and shells thickness 41–44 nm. The
recorded σdc is 2.9 × 10−8–1.45 × 10−7 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.
