The CV curve at the Ex-CC electrode is close to the ideal rectangular shape, indicating smaller internal resistance in the electrode, while CC shows a very poor rectangular shape. Although carbon fiber is a highly conductive substrate, carbon fibers in CC have poor affinity with electrolytes due...
The voltage threshold Vth was defined as the local minimum on the CV curve. The elemental composition of the sample was characterized using X-ray photoelectron spectroscopy (XPS). The measurement and analysis was carried out using a Thermo Scientific K-alpha XPS tool with a monochromatic aluminum...
aThen X-ray photoelectron spectroscopy (XPS) was introduced to determine the surface chemical composition and properties of the carbon fiber 然后X-射线介绍 (光电子) 分光学XPS确定碳纤维的表面化学成分和物产 [translate] 英语翻译 日语翻译 韩语翻译 德语翻译 法语翻译 俄语翻译 阿拉伯语翻译 西班牙语翻译 ...
The deterioration of crystal structure was observed during the XRD studies and XPS revealed a decrease in the peak corresponding to C–C bond, attributed to the oxidation of material by AO [37]. Additionally, a slight decrease in N components and a significant increase in O components were ...
Du Pont E‐120 high modulus pitch‐based carbon fiber was galvanostatically oxidized in (NH4)2CO3 solution and analyzed with both core level and valence band XPS. Compared to the untreated E‐120 fiber, the galvanostatically oxidized fiber had a very much higher oxygen content on its surface....
Which is better aluminum or magnesium? How about carbon fiber? We take an in-depth look at the most popular materials used in phones, laptops and tablets today.
Seen from the degra- dation kinetic curve of the composite (Fig. 3c) and the X-ray photoemission spectroscopy (XPS) spectra of CFs (Supplementary Fig. 17), the complete depolymerization time of the BAPP-PHT is B20 h. Taking into account the generation time of BAPP, the total degradation ...
