Structural, Optical and Electrical Properties of MnO2 / MWCNTs/PVA Nanocomposite
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 2019, Vol 16, Issue 1
Abstract
Manganese dioxide/multi-walled carbon nanotubes MnO2/ MWCNTs nanocomposite are synthesized by hydrothermal method. The crystallographic information of the acid-treated MWCNTs and the MnO2/ modified MWCNTs nanocomposite were characterized by X-ray diffraction (XRD),Transmission electron microscope (TEM )and FT-IR spectra. Optical and electrical properties of MnO2 / MWCNTs / PVA nanocomposite thin film with different concentration were studied .UV-VIS absorption spectra shift, at different exposing time , indicated the sensitivity to UV radiation. Optical band gap decreases with increasing time of radiation. Electrical properties of MnO2 / MWCNTs / PVA nanocomposite thin films with different concentration according to different frequency and exposing time of UV radiation showed semiconducting properties and sensitivity to UV radiation.
