Environment-friendly carboxymethyl cellulose (CMC) hydrogel beads were successfully prepared using epichlorohydrin (ECH) as a crosslinking agent in the suspension of fluid wax. There was an...

In the XRD diffractogram (Fig. 2f), CMC exhibited a crystalline structure with the typical diffraction peak at 20° 2θ and no other diffraction peaks of contaminants, indicating a high purity of...

2020年6月1日 · The morphology of CMC showed ribbon and rod-like shapes with a diameter of 25−50 μm. The XRD patterns indicated that the crystal structure of CMC changed as the peaks at 16.17° and 22.77° disappeared and the new peaks at 27.46°, 31.78° and 45.37° appeared.

2023年1月20日 · The amorphous nature of CMC was revealed by XRD analysis, with the intensity of the typical peak of virgin polymer in the nanocomposite spectrum decreasing dramatically as the doping amount was...

2019年5月1日 · The features of interaction between CMC and PVA were investigated using X-ray diffraction (XRD), and infrared (IR) spectroscopy to disclose the reduction of crystallinity of the HPe system. Morphological properties observed by Scanning electron microscopy (SEM) confirmed the homogeneity of the HPe system.

The structure and particle size of the TiO2 nanoparticles, embedded in the CMC matrix, were identified by X-ray diffraction (XRD), and transmission electron microscopy (TEM) techniques, with ...

2018年1月1日 · X-ray diffraction (XRD) is an efficient tool to investigate the degree of crystallinity for polymeric materials. XRD patterns for CMC and CMC-g-P(SPMA) hydrogel are represented in Fig. 1 D. CMC shows sharp reflections at 9.

2020年9月13日 · CMC films incorporating different types of clay NPs, modified by Ag and Cu ions were prepared and their physico-mechanical and antibacterial properties were evaluated. XRD patterns for modified clays with Ag and Cu ions showed that they were effectively located in the interlayer space of C30B and MMT clay NPs and increased their interlayer spacing.

In the present study, a novel crosslinked pH-responsive hydrogel with high water-retention ability was prepared from CMC and HEC. The properties of the prepared CMC/HEC crosslinked hydrogel were characterized using Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM).
