Characterization and optical properties of polyaniline-MWCNT-ZnS nanocomposites

Abstract

Polyaniline (PANI)-MWCNT-Zinc sulfide (ZnS) nanocomposites have been synthesized at room temperature by in situ polymerization of aniline in presence of MWCNT and negatively charged ZnS nanoparticles. The nanocomposites were characterized using HRTEM, RAMAN, FTIR, UV-VIS absorptions spectroscopy and photoluminescence (PL) spectroscopy. From HRTEM the estimated particle diameter of different nanocomposites are 3.21 nm. PL measurements indicates that the incorporation of ZnS nanoparticles in PANI-MWCNT enhance the PL emission and occurrence of red shift.
