XRD spectra recorded for the different wood species, EVOH, …
Figure 1 shows the XRD patterns of LLDPE, EVOH, the four wood species, and the four WPCs. LLDPE has three main crystalline diffraction peaks at 2 of 21.58, 23.78, and 36.28, ...
Elaborating conspicuously low hydrogen permeability EVOH …
2024年8月1日 · Combined with the FTIR test results with the XRD diffraction pattern of EVOH, it can be reasonably deduced that a high-pressure hydrogen environment has induced the polymeric chain to partially disorder and to be disrupted, thus providing a more permeation pathway for hydrogen molecules to travel through.
Preparation and Characterization of Electrospun EVOH/Ti
2024年2月11日 · To investigate the effect of the Ti 3 C 2 content on the structure of the electrospun EVOH composite fibers, the XRD patterns and FTIR spectra of the electrospun EVOH/Ti 3 C 2 fibrous membranes were analyzed, as shown in Figure 3.
Characterization, biodegradation and cytotoxicity of thermoplastic ...
2022年12月15日 · Their biodegradability and cytotoxicity were studied by different techniques (XRD, DSC, TGA, CA, ATR-FTIR, SEM). TPS presence significantly affected copolymer behavior, as confirmed by the appearance of O H IR 1000–1170 cm −1 bands and overall reduction of EVOH crystallinity, melting point, thermal stability and hydrophobicity ...
