Figure 2 shows the XRD patterns comparison between PS with PS-S and PS-SD composites at different sulfur loading. PS shows a broad XRD peak at 2θ = 20° confirming its amorphous nature,...

The XRD of an unfilled and filled PS polymeric matrix containing MnTPPCl is shown in Fig. 2. Unfilled PS has two large diffraction peaks at 2θ = 9.5 and 19.43, which confirms the produced...

Polyamide 6 (PA6) and polystyrene (PS) nanotubes were successfully fabricated by polymer solution-wetting method. High-resolution transmission electron microscopy (HRTEM), X-ray diffraction...

2016年9月1日 · The prepared PS as well as PS/Co Al LDH (1–7 wt.%) nanocomposites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), rheological analysis, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The XRD results suggested the formation of ...

2016年1月1日 · Semiconductor industries use XRD to determine crystallite size, lattice strain, chemical composition, and crystal orientation. Biological samples such as DNA, vitamins, protein, and drug synthesis, use XRD to identify the elemental composition and their crystal structure.

2020年4月1日 · xrd物相定性分析是将样品的衍射数据与已知物相的衍射数据或图谱进行对比，一旦二者相符，则表明待测物相与已知物相是同一物相。 灵敏度较低，一般只能测定样品中含量在1%以上的物相，同时，定量测定的准确度也不高，一般在1%的数量级。

通过 XRD 图谱和高倍率的透射电子照片判断制得石墨烯为无定形。 通 过 SEM 照片观察到制得的，石墨烯片层具有很强的褶皱，石墨烯呈片层堆叠形 貌。 但是石墨烯片层的堆积较致密堆积，这将减少锂离子与石墨烯的接触面积， 从而影响到锂离子的嵌入与脱出，造成电池的容量较低。 图 2.7 为 GO 与 PS 复合结构的 SEM 图像，由 SEM 图像可以清楚地观察到 GO 与 PS 球形成的核壳结构，图片中的球形的粒子表明复合结构保留了 PS 的球 形结构，而与纯 PS 球相比，复合结 …

2018年9月1日 · In XRD pattern of PS shown a certain broad band at 2θ 20.44° which is characteristics peak of polystyrene card No. (041–1802) while in XRD analysis for SPS, a small peak is observed at 2θ 9.3° which is correlated to the presence of sulphure.

2020年1月13日 · Their effects on the morphology, and mechanical, thermal, and rheological properties of PS were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and x-ray diffraction (XRD), tensile and impact tests, differential scanning calorimetry (DSC), and melt flow index measurements, respectively.

2021年6月3日 · X-ray diffraction (XRD), Fourier transform infrared (FT-IR), High-resolution scanning electron microscope (HRSEM), and UV–Vis techniques are used to characterize the nanocomposites. XRD, HRSEM, and FT-IR results indicate that PS and NiO nanoparticles have a good interaction and a high degree of complexity.
