Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) identified polyethylene (PE) and isotactic polypropylene (iPP) as the main polymers present in the ropes, with a...

Structural properties of HDPE+%ZrO2 polymer nanocomposites thin films of 80-100μm thicknesses were investigated using SANS, XRD, Laser Raman and FTIR spectroscopy. The mass fraction of the filler...

While HDPE is crystalline enough to characterize further, this paper focuses on the capabilities of benchtop X-ray diffraction (XRD) to analyze the % crystallinity and crystallite size of the films. XRD has long been considered a gold standard method for material analysis.

2021年11月3日 · We explored high density polyethylene (HDPE) both on its reactants Hugoniot (⁠ < 10.12 GPa) and within its transition region (24.3 GPa) where HDPE is hypothesized to decompose from reactants to products. With x-ray diffraction, we observed both polymer chain compression and crystal structure reorientation from orthorhombic to monoclinic above ...

The XRD patterns were observed at 2θ angles of 33.33°, 38.64°, 44.43°, 55.90°, and 58.55°, indicating the presence of cadmium oxide nanoparticles.

2025年3月6日 · X-ray diffraction (XRD) analysis revealed that the addition of alumina nanoparticles to the HDPE polymer matrix did not significantly alter the semi-crystalline lattice structure of HDPE. Atomic force microscopy (AFM) showed that incorporating alumina powder as filler affected structural parameters such as surface roughness and mean grain size.

2019年5月25日 · In order to evaluate the alteration of HDPE crystal structure after ECAP deformation as well as calculation of crystallinity (X XRD), X-ray diffraction (XRD) was measured by X’Pert Pro Phillips diffractometer using CuKα radiation (λ = 0.15406 nm) between 2θ of 10° and 50° with 0.02° scan increments.

2023年11月6日 · FTIR spectroscopy reveals the bonding strength and molecular structure of the HDPE–MWCNT composite. XRD and Raman analysis provide insights into the impact on the crystalline nature, phase data, and chemical structure of HDPE upon the addition of MWCNT.

density polyethylene (HDPE) have been studied by Fourier transform infrared (FTIR), UV-vis spectroscopic, and x-ray diffraction (XRD) techniques. A Co60gamma source (with a dose rate of 1.707 kGy/hr) has been used up to the total dose of 570 kGy. There are …

2019年8月1日 · XRD peak splitting in the HDPE + GO and the HDPE + γ-Al 2 O 3 nanocomposites suggest the emergence of a concurrent orthorhombic HDPE phase. Formation of new phases was also supported by DSC analyses showing broad and multimodal melting peaks.
