37,41,42 The successful attaching of –NH2 to the HPC was confirmed by FTIR spectra, X-ray photoelectron spectroscopy (XPS), and elemental analysis (EA) (Figure S2; Table S2). Compared with HPC, several distinguished IR peaks appeared in sample HPC–NH2 at 898, 1,589, and 3,465 cm...
Unsaturated polyesterFlame retardancyImpact performanceA novel phosphorus-containing flame retardant PZN@UiO-66-NH2 was synthesized by covalent bonding between HCCP and UiO-66-NH2, and applied in unsaturated polyester (UPR). The Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron energy ...
The characterization of the prepared nano-materials were performed using different analyses such as FTIR, XRD, SEM, EDS, TEM, and BET and the results proved the successful synthesize of UiO-66-NH2/ CNTs nanocomposite. The corrosion protection performance of the coated panels was investigated by ...
The FTIR spectra of CNTs, UiO-66-NH2and UiO-66-NH2/CNTs hybrid nanocomposite are shown in Fig.3a. The UiO-66-NH2spectrum illustrates three specific peaks (marked with small arrows) at 1400, 1580, and 1655 cm−1. The FTIR peak at around 1400 cm−1attributed to symmetric vibration of...
The FTIR spectrum of UiO-66-NH2 was consistent with the results that had been reported [39, 41] and used for monitoring the changes that occurred during the synthesizing process and encapsulation. The existence of OXA in UiO-66-NH2 has been confirmed since the OXA loaded UiO-66-NH2 had ...
XRD, FTIR and NMR analyses revealed that a series of reactions occurred in the dehydrogenation of the composite. The prior interaction between LiH and Mg–B–N–H yielded intermediate LiBH4, which subsequently reacted with Mg(NH2)2 and LiH in molar ratio of 1:6:9 to form Li2Mg2(NH)3 ...
The single-crystal FTIR spectrum has a doublet of intense bands at 3670 and 3589 cm–1, which are assigned to the n3and n1stretching modes of the H2O molecule, respectively. A very intense and sharp peak at 1620 cm–1is assigned to the n2bending vibration. In the near-infrared region ...
The FTIR spectrum of NH2-MIL-125(Ti) showed a -NH2stretching vibration absorption peak from the organic ligand of NH2-MIL-125(Ti) near 3400 cm−1inFigure 1F. The absorption at 400–800 cm−1was derived from the O−Ti−O stretching vibration [33]. The peaks near 1500 and 1600 ...
replacing dimethylformamide by 50 and 75% acetone as substitute solvent. The physicochemical properties of the materials were evaluated by X-ray diffraction (XRD), Infrared Spectrometry with Fourier Transform (FTIR), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), microwave ...
The Co2O3‐NH2‐MCM‐41was characterized by Scanning Electron Microscope (SEM), Brunauer‐Emmett‐Teller (BET), X‐ray diffraction (XRD) and Fourier transform infrared spectra (FTIR). Electrochemical measurements including cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS)were ...
