摘要: An in-situ uniaxial deformation study of nylon 6–clay hybrid (NCH) nanocomposites was carried out using simultaneous wide-angle x-ray diffraction (WAXD) and small-angle scattering (SAXS) techniques with synchrotron radiation. This nanocomposite system exhibited the partial exfoliated clay morphology. The WAXD patterns along through-and edge-views from as-pressed film samples indicated that both platelets 6 crystallites were parallel to plane but oriented randomly in plane. During deformation, orientation molecular axis crystals increased strain decreased content. behavior could be attributed rotation during which hindered crystals. corresponding tensile mechanical properties elongation at break modulus strength concentration, has been observed before.
