X-Ray diffraction (XRD) pattern of polypropylene (PP), polyethylene (PE …
According to previous research, the XRD patterns of three different types of microplastics (PE, PVC and PS) show two strong sharp peaks at 2 of 21.1° and 23.4° for PE, no sharp peak for PVC and...
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.
Typical XRD patterns from polyethylene: LDPE/LLDPE (PE),.
Low-density polyethylene (LDPE), known for its good dielectric characteristics and wide use in electrical insulation have been investigated for the desired applications. However, the...
Methods of determining the degree of crystallinity of polymers …
In these methods, the densities of crystalline and amorphous phases, the peaks in infrared (IR), solid-state 13 C nuclear magnetic resonance (NMR), and Raman spectra, various data in XRD pattern (such as peak height, the fields of phases) and …
Effect of Crystallinity of Polyethylene with Different Densities …
In this paper, the XRD, DSC, DC breakdown and conductance characteristics at 5–200 kV/mm of four kinds of polyethylene with different densities (LDPE, LLDPE, MDPE, HDPE) were measured based on room temperature, and the main conclusions were as follows:
In situ x-ray diffraction of high density polyethylene during …
Nov 3, 2021 · 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.
For XRD measurements, sheet samples of PE (Polyethylene) and PP (Polypropylene) were measured in transmission geometry for five minutes under Cu-Kα radiation. The quality of the data obtained with the ARL EQUINOX 100 benchtop instrument is comparable to data from a typical high-power floor standing instrument.
Calculation of the degree of crystallinity of HDPE/GNPs ... - Springer
Jan 10, 2023 · XRD and vibrational spectroscopy measure long-range/intermolecular order and short-range/intramolecular order, respectively. XRD uses either individual peaks from the pattern or the complete pattern to establish a correlation between peak intensity and/or cumulative area and phase composition.
Figure 8 X-ray diffraction (XRD) spectra of 100% high-density...
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...
Investigation of Three Types of Polyethylene Films - AZoM.com
Jun 5, 2020 · XRD is able to perform various analyses, ranging from phase identification and quantification for medium and highly crystalline plastics, to the determination of crystallinity percentage and crystallite size materials with lower crystallinity.
