Small angle x-ray scattering technique in studying the morphological structure of thermoplastic natural rubber

Abstract

Thermoplastic natural rubber sample is found isotropic based on Small Angle X-Ray Scattering (SAXS) pattern. Morphological interpretation was deduced based on ideal lamellar morphology using 1-D correlation function. The fitting was carried out using Porod tail model and Vonk for backextra/polated model. It is found that the long period value is 15.7nm which is comparable to results obtained from Lorenzt corrected profile, 20nm. Crystalline thickness and amorphous thickness was found as 13.f and 2.31nm respectively
