X-ray diffraction analysis (XRD) is one of the microstructural analysis methods used for the identification of aystaUinity of polymers, recognition of crystalline phases (polymorphism), and orientation of polymers. Olivato et al. [64] prepared starch/ polyester nanobiocomposites based on sepiolite clay, and from wide-angle XRD they showed no significant alteration of the crystalline structures of PBAT and starch induced by the sepiohte clay. Scaffaro et al. [155] added OMM to HDPE/PA-6 blends using a co-rotating TSE and characterized by SEM, TEM, and XRD analyses. They... 

HDPE, NR and thermoplastic tapioca starch (TPS). Several previous studies have reported that blends with starch exhibit a marked decrease in tensile properties because the incorporation of starch interferes in the adhesion between the component phases.Therefore, based on this research work, the mechanical properties were improved by NR vulcanization, which compensated for the deterioration in properties due to TPS loading.
