WebMay 26, 2024 · Table 4 presents crystallinity index values of the dyed fabrics. The crystallinity index could be calculated for every fabric. It is clearly seen that crystallinity index is coherent to the elongation at break of yarns or fabrics (see Figure 8 and Figure 10). Higher crystallinity index corresponds to lower elongation at break values. WebThe Avrami equation describes how solids transform from one phase to another at constant temperature. It can specifically describe the kinetics of crystallisation , can be applied …
WebApr 8, 2024 · XRD profiles were also used to determine the crystallinity index of the cellulose hydrogel prepared under each hydrostatic pressure using the Segal method [Equation (3)] (Fig. 4, Table S16). The results showed that the crystallinity of the cellulose hydrogels prepared at 0.1–250 MPa approximated 46% and that the crystallinity hardly … WebTheir crystallinity degrees were determined using Origin® software, according to the equation X C (%) = I C / (I C + I A) x 100, where Xc is the crystallinity degree; Ic is the sum of the areas under the crystalline peaks and I A is the area of the amorphous halo. The peaks were deconvoluted using Gaussian peak function.
Crystallinity refers to the degree of structural order in a solid. In a crystal, the atoms or molecules are arranged in a regular, periodic manner. The degree of crystallinity has a big influence on hardness, density, transparency and diffusion. In an ideal gas, the relative positions of the atoms or molecules are completely random. Amorphous materials, such as liquids and glasses, represent an intermediate case, having order over short distances (a few atomic or molecular spacings) but n… WebApr 9, 2024 · They were characterized by a lower crystallinity degree of 70–74%, a moderate porosity of 12–28%, liquid permeability of up to 12–26 L m−2 h−1 bar−1, a mean flow pore size of up to 12–17 nm, and a higher tensile strength of 11–20 MPa. ... and calculated using Equation (2) for the crystallinity degree (α) of UHMWPE.
