2024年12月1日 · The ESCALAB 250Xi X-ray photoelectron spectroscopy (XPS) was used to obtain the C1s spectra of sisal fiber (Al K, 30 eV pass energy). The micromorphology of sisal fibers was observed using a scanning electron microscope (TESCAN VEGA 3).

2010年12月1日 · In X-ray photoelectron spectroscopy (XPS) analysis, pulp sisal fibres (SFs) were first formed into small sheets (diameter: 20 mm, basis weight: 80 g/m 2) by using screen filter (200 mesh), and thereafter dried at room temperature before extraction and XPS measurements.

2024年3月6日 · e) 利用 X 射线光电子能谱 （XPS）对茜草、碱剑麻和 Q-sisal超细纤维进行分析，探测到 392 至 410 eV 的特征峰。 在 Q 剑麻XPS 光谱中，在 402 eV 处出现了一个新的峰值（对应于季铵盐的 N 峰）。

2024年1月8日 · First, the effect of grafting IPMS on sisal cellulose was investigated using various analytical methods, including SEM, FT-IR spectroscopy, XRD, TGA, and XPS. Morphological changes in the sisal fibers after different treatments were investigated using SEM.

2014年2月28日 · Combining XPS and ToF-SIMS provides a powerful method for analyzing both unmodified and modified cellulosic fibers: XPS technique provides semi-quantitative information regarding the elemental composition of the surface, while ToF-SIMS data characterizes the chemical surface in detail (Freire et al. 2006; Guezguez et al. 2013; Cunha et al ...

2024年10月18日 · This study explores the development and characterization of epoxy resin composites reinforced with palm kernel shell (PKS) particulate and sisal fibers, ai

Bio-based films were prepared from LiCl/DMAc solutions containing sisal cellulose esters (acetates, butyrates and hexanoates) with different degrees of substitution (DS 0.7-1.8) and solutions ...

2014年4月9日 · Different analytical techniques were employed to examine effect of surface treatment, including Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and thermogravimetric analysis (TGA) in nitrogen and air.
