The XRD analysis of the incorporated films indicated that the NiO NPs crystallinity increased at expense of the CMC/PVA/PEDOT:PSS composites. Fourier Transform Infrared (FTIR) examination revealed the main absorption vibrational peaks of CMC, PVA, PEDOT:PSS, and Ni-O, whose intensities changed ...
CMC/PVA/HEAIon beam analysisFTIRUV–VisHydrogelPVA/CMC/HEA based cross-linked hydrogels were synthesized. These were utilized as matrix chloramphenicol drug releasing systems. Combination of different analytical techniques was applied to understand drug releasing process. Ion beam analysis (IBA) ...
PVA/CMC/ attapulgite clay composite hydrogel membranes were char- acterized by FTIR, SEM, swelling tests, mechanical/ther- mal stability, as well as antimicrobial activity. The obtained results showed that, the properties of composite hydrogel membranes have significantly affected by the used CA con...
以磷酸作为交联引发剂和质子源,用戊二醛(GA)交联聚乙烯醇(PVA)制备 PVA-H3 PO4凝胶聚合物电解质膜.采用 X-射线衍射(XRD),傅立叶变换红外光谱(FTIR),热重分析(TGA)对制备的凝胶聚合物电解质膜进行了表征,并采用交流阻抗法研究了凝胶聚合物电解质膜的导电性能,分析了磷酸含量对凝胶聚合物电解质膜质子电导率的影...
The complexation between ZnO/TiO2 NPs and the polymer matrix could also influence the FTIR spectra. PVA/PEO composite exhibits transmittance bands at 2876 cm-1, which are associated with –CH2 asymmetric stretching and –CH asymmetric stretching, and 1471 cm−1, which have been related to C-...
(FTIR) confirmed a strong interaction between the PEO/PVA blend and the CuO NPs. UV-Vis spectrophotometry was employed to determine the direct and indirect optical bandgaps using Tauc plots. The finding showed that when the concentration of nanoparticles increased, the indirect and direct bandgaps...
It is critical to strike a balance between energy needs and environmental concerns in the current situation. The use of biopolymers such as starch, cellulose, chitosan, carboxymethyl cellulose (CMC), and gellan gum over the synthetic polymers as a host in electrolytes is exciting due to its exce...
FTIR–ATR spectroscopy constitutes a fundamental technique for identifying functional groups, such as those indicative of the typical cross-linking in hydrogels, as well as the presence of entrapped pesticides or fertilizers. In addition, this technique has the capability to unveil unreacted precursors ...
The structural evolution of electrospun nanofiber was analyzed by differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR). Although PLA and PVA were still miscible in the concentration range used, the latter could crystallize independently after electrospinning. According ...
