WebIts level of crystallinity is one of its most challenging and least understood characteristics. PEEK is a semi-crystalline thermoplastic polymer, which means that a portion of its molecules aligns and forms crystals while the rest remains amorphous.
WebJan 19, 2024 · Cellulose is crystallized by plants and other organisms into fibrous nanocrystals. The mechanical properties of these nanofibers and the formation of helical superstructures with energy dissipating and adaptive optical properties depend on the ordering of polysaccharide chains within these nanocrystals, which is typically measured … WebIntegration Method analysis The integration method uses a straight background line and compares the area under the entire curve with the area under the crystalline peaks using the following equation. %Crystallinity = [ (area under the crystalline peaks)/ (area under all peaks)] *100 Analysis
WebMay 25, 2024 · The results of density, differential scanning calorimetry (DSC) and X-ray diffraction (XRD) represent a decrease in the polymer’s crystallinity after deformation, which is more evident after three passes of ECAP. Moreover, a phenomenological mechanism is proposed to explain the variations of crystallinity after ECAP processing.
