Deconvolution of X-ray Diffraction Spectrum of Polypropylene

Abstract

Deconvolution methods have been used to evaluate degree of crystallinity and particle size from diffractogram of polypropylene(PP). The deconvolution method is used to separate the various peaks from the total XRD spectrum and it is successful in separating the crystalline, amorphous and background regions of a diffractogram. The degree of crystallinity of PP is calculated to be 49%. The particle size of crystallites in different crystalline phase is calculated using Scherrer equation.
