Witryna12 maj 2024 · A N2200-based micro-morphology is formed guided by N2200 domains. The results confirm that the crystallization sequence is one of the most important factors to determine the micro-morphology structure in all-crystalline polymer blends. WitrynaX-ray diffraction is used most frequently to investigate the structure of biocomposites with embedded nanostructure. The XRD spectra of GOnPs sheet showed (Fig. 12.5A) the characteristic GOnPs peak appearing at 2θ=11.1 degrees, corresponding to a lattice d-spacing of 0.78 nm.For the GOnPs-PCL meshes, an XRD peak (Fig. 12.5B) …
