Structure Development during Shear Flow-Induced Crystallization of i-PP: In-Situ Small-Angle X-ray Scattering Study
Rajesh H. Somani,Benjamin S. Hsiao,Aurora Nogales,Srivatsan Srinivas,Andy H. Tsou,Igors Sics,F. J. Baltá-Calleja,Tiberio A. Ezquerra +7 more
TL;DR: In this paper, small-angle X-ray scattering (SAXS) was used to follow orientation-induced crystallization of isotactic polypropylene (i-PP) in the subcooled melt at 140 °C after step shear under isothermal conditions.
Journal ArticleDOI
On the structure and morphology of polyvinylidene fluoride-nanoclay nanocomposites
TL;DR: In this paper, the structure and morphology of polyvinylidene fluoride (PVDF)-nanoclay nanocomposites were investigated by wide angle X-ray diffraction (WAXD), polarized light microscopy and transmission electron microscopy (TEM) techniques.
Journal ArticleDOI
Orientation and Crystallization of Natural Rubber Network As Revealed by WAXD Using Synchrotron Radiation
Masatoshi Tosaka,Syozo Murakami,Sirilux Poompradub,Shinzo Kohjiya,Yuko Ikeda,Shigeyuki Toki,Igors Sics,Benjamin S. Hsiao +7 more
TL;DR: In this article, the onset strain of crystallization was almost independent of the volume of the unit cell, and the deformation of crystal lattice with nominal stress was detected, and strain-induced crystallites were found to be responsible for the increased modulus upon elongation.
Journal ArticleDOI
New Insights into Structural Development in Natural Rubber during Uniaxial Deformation by In Situ Synchrotron X-ray Diffraction
Shigeyuki Toki,Igors Sics,Shaofeng Ran,Lizui Liu,Benjamin S. Hsiao,Syozo Murakami,Kazunobu Senoo,Shinzo Kohjiya +7 more
TL;DR: In this paper, the molecular orientation and strain-induced crystallization of vulcanized natural rubber during uniaxial deformation were studied via in situ synchrotron wide-angle X-ray diffraction (WAXD).
Journal ArticleDOI
Shear-Induced Crystallization Precursor Studies in Model Polyethylene Blends by in-Situ Rheo-SAXS and Rheo-WAXD
Ling Yang,Rajesh H. Somani,Igors Sics,Benjamin S. Hsiao,Rainer Kolb,Hitesh Fruitwala,Christine Ong +6 more
TL;DR: In this article, the development of shear-induced crystallization precursor structure was studied by in-situ rheo-SAXS (small-angle X-ray scattering) and rheoe-WAXD (wide-angle x-ray diffraction) techniques using binary polymer blends of high and low molecular weight polyethylenes near their nominal melting temperatures.
