The crystallographic information of the acid-treated MWCNTs and the MnO<sub>2</sub>/ modified MWCNTs nanocomposite were characterized by X-ray diffraction (XRD),Transmission electron microscope (TEM )and  FT-IR spectra. Optical and electrical properties of MnO<sub>2</sub> / 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 MnO<sub>2</sub> / 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.</p>}, number={1}, journal={JOURNAL OF ADVANCES IN PHYSICS}, author={Elmahy, Safaa Kamel}, year={2019}, month={Feb.}, pages={8–18} }
