Using solution casting method, PVA based polymer composites films with various concentrations of CdCl2 were prepared. Prepared polymer composites films were investigated using XRD. Crystallite size for different concentrations of CdCl2 are computed here using Williamson and Hall plot (WH plot), an in-house program developed by us. To correlate between two independent physical parameters size and conductivity, we have chosen functional data analysis to estimate the maxima and minima in these polymer composites systems.

Pair correlation and line profile analyses of X-ray data obtained for some man-made polymers have been carried out in this report. Results obtained show that the pair correlation is pronounced in the region of 2Å and dies away for regions greater than 10Å in general for all the samples in the neighborhood of the point where X-rays are incident on the sample. Complementary to this study, line profile analysis shows that the crystallite size and strain obtained from Williamson-Hall plot method in these polymers do change significantly. This information is in no way connected to the results of pair correlation study [ABSTRACT FROM AUTHOR]
