2021年1月1日 · The chemical bonding of the coated CIPs is detected using the Fourier Transform Infrared Spectroscopy (FT-IR). The saturation magnetization (M s) of pure and coated CIPs is 245 emu/g and 120 emu/g, respectively, at 15 kOe, which is obtained by using a superconducting quantum interface device (SQUID). The rheology flow curve properties show that ...

CuInP2S6 (CIPS) is an emerging layered ferroelectric material with a TC above room temperature. When synthesized with Cu deficiencies (i.e., Cu1-xIn1+x/3P2S6), the material...

2021年9月22日 · 为进一步分析电解液中li + 溶剂化结构对电极性能的影响，研究者利用ftir对电解液进行了测试分析。 结果表明，当LiPF 6 溶解到EMC或MA溶剂后，在EMC电解液中，位于1750 cm -1 对应的C=O 峰会移动到1718 cm -1 ，形成Li + -EMC配位峰，同样在MA电解液中，位于1747 cm -1 处的C=O ...

2023年1月30日 · Achieving resistance to sedimentation of carbonyl iron powders (CIPs) in ethanol is important to fabricate reliable magnetorheological suspensions. The traditional method to improve the sedimentation stability is to add dispersants, but this approach can suffer from high costs and toxicity of added surfactants.

2022年4月2日 · 采用ATR-FTIR光谱并结合二维相关光谱衍生的外扰相关移动窗口(perturbation-correlation moving window，PCMW)技术研究了不同浓度尿素水溶液(0，20 wt%、40 wt%和50 wt%)在黏胶纤维膜中的扩散行为，在分子水平揭示了尿素溶液的动态扩散行为以及与黏胶纤维的相互作用机制[49]. 从 ...

2006年1月26日 · Supersaturated MgSO4 aerosols and dilute MgSO4 solutions were studied by FTIR spectroscopic techniques (i.e., aerosol flow tube (AFT) and attenuated total reflection (ATR)). The hygroscopic properties of MgSO4 aerosols were investigated with results in good agreement with previous measurements by a …

IR spectra and Kip values for LiNCO, NaNCO and KNCO in DMSO. In this work the properties of cyanate and azide ion pairs with Li+, Na+, K+, and NH4 + in DMSO or other bulk solvents were characterized by infrared spectroscopy.

Supersaturated MgSO4 aerosols and dilute MgSO4 solutions were studied by FTIR spectroscopic techniques (i.e., aerosol flow tube (AFT) and attenuated total reflection (ATR)). The hygroscopic properties of MgSO4 aerosols were investigated with results in good agreement with previous measurements by a scanning electrodynamic balance (SEDB).

通过红外光谱 (FTIR)、扫描电子显微镜 (SEM)、X射线衍射仪 (XRD)和矢量网络分析仪 (VNA)等测试技术对所制备复合材料的微观特征和电磁性能进行分析对比。 研究不同羰基铁 (CIP)的体积占比与复合材料电磁波吸收性能和防腐蚀性能之间的关系。 结果 通过KH560改性后的羰基铁与环氧树脂混合均匀，形成了紧密的网络结构。 羰基铁粉为片状，长度为3~10 μm。当羰基铁粉的体积分数为20%时，样品的吸波性能和防腐性能较好，综合性能相对最佳。所制备的样品在较宽范围内 …

In this study, methyl vinyl phenyl silicone rubber (MPVQ)/carbonyl iron particles (CIPs)/graphene (GR) composites were prepared by mechanical blending, and the effects of thermal-ageing...
