A facile synthesis of a novel optoelectric material: a nanocomposite of SWCNT/ZnO nanostructures embedded in sulfonated polyaniline

摘要

Functionalized single-walled carbon nanotubes(f-SWCNTs)hybridized with freshly prepared zinc oxide(ZnO)nanocrystals have been found to be good luminescent material with tuned emission properties.A three-phase nanocomposite of sulfonated polyaniline embedded with such SWCNT/ZnO nanostructures has been prepared by a simple solution mixing chemical process and characterized by using high-resolution transmission electron microscopy,X-ray diffractometry,Raman spectroscopy,Fourier transform infrared spectroscopy,and thermogravimetric analysis.The study of UVvisible absorption and photoluminescence spectroscopies reveal that the ternary polymer nanocomposite is a luminescent material with enhanced emission intensity.Also an increase in DC conductivity indicates that the nanocomposite is also a good conductive material,satisfying Mott’s variable range hopping model for a two-dimensional conduction.Such a three-phase nanocomposite may find extensive application in dye-sensitized solar cells,sensors,and supercapacitors.
