“…In situ investigations of the material morphology and structure, and mechanical properties has been the focus of rubber research for decades [20]. X-ray scattering techniques, such as small-angle Xray scattering (SAXS) and wide-angle X-ray scattering (WAXS) are well known for the study of the microstructure of polymer-based composite materials, including the nanofiller dispersion and distribution or the macromolecular and/or filler orientation in anisotropic systems [21].…”
