Abstract
Polyvinyl alcohol- polypyrrole (PVA-PPy) nanocomposites with metal chlorides (FeCl3, NiCl2, CuCl2 and ZnCl2) have been synthesized by chemical oxidative polymerization method. 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
Highlights
Crystallization behavior of semi crystalline polymer has been extensively investigated due to their technological and theoretical importance
The prepared polyvinyl alcohol (PVA)/PPY/ CuCl2 nano composites in the present study are expected to be more useful in photonic and electronic device applications, Alabur Manjunath et al.[16] .The results obtained in the present work is of the same order as it is reported in the literature, Ahmed hasim et al [17]

Summary
Crystallization behavior of semi crystalline polymer has been extensively investigated due to their technological and theoretical importance. A vinyl polymer, namely polyvinyl alcohol (PVA) is semi crystalline, water soluble, and low electrical conductivity material. The Polyvinyl/ polypyrrole (PVA/PPY) Nan composite with metal chlorides (FeCl3, NiCl2, CuCl2 and ZnCl2) have been characterized by using various techniques such as FTIR, XRD, TEM and DC electrical conductivity. The XRD and TEM are performed in order to confirm the crystallization behavior of PVA/PPY metals Nan composite. In this regard we have made an attempt to study the electrical conductivity of pure PVA, PPY and nanocomposite with metals to know the influence of metals on pure polymer in answering better electrical conductivity
