These synthesized nanocomposites are characterized by using FTIR, X-ray diffraction, Transition electron microscope (TEM) and Conductivity measurement. TEM exhibit that all of the composites have uniform sizes and morphologies.  The diameter of PVA/PPy nanocompsite is 58nm when the metals added to the PVA/PPy the diameters becomes smaller. The variation of electrical conductivity (log ?) with 1000/T for PVA/PPy nanocomposite with metal chlorides revealed that the increase in conductivity s at temperature (393K) with added metals can be attributed to the creation of induced charge carriers in PVA/PPy matrix</p>}, number={1}, journal={JOURNAL OF ADVANCES IN PHYSICS}, author={Shahin, Naglaa and Abd El Hamid, Reham Kamal}, year={2019}, month={Apr.}, pages={55–63} }
