在xrd图谱中，2θ角度对应的是x射线被样品内原子平面反射的角度，不同的角度对应材料内部的不同晶面间距。 如果在23度处出现峰，哪怕是很小的，可能意味着在该弹性体中共聚物中存在某种有序结构或者特定的结晶相，尽管这种有序程度不高。

2023年3月28日 · The crystallite sizes (L) of all PA and PA-Compounds can be determined from the XRD data according to the Scherrer expression: L = K × λ β × cos θ , (3) where K is the Scherrer factor ( K = 0.9), λ is the X-ray wavelength ( λ = 0.15406 nm), β is the measured half-width of the respective peak, and θ is the Bragg angle.

X-ray diffraction (XRD) patterns of all studied samples in range 3–45° 2Θ with evaluated α and γ phases of polyamide 12 and detail of studied main γ-PA diffractions in range 18–25° 2Θ. Intensity of the peaks is changing during laser sintering process.

采用动态力学分析、x射线衍射(xrd)和扫描电子显微镜(sem)等方法研究了pa6复合纤维的结晶动力学和界面结合对其拉伸性能的影响 田银彩等则发现添加石墨烯诱导PA6由γ晶型向α晶型转变，控制适度的石墨烯含量可以保证其分散均匀并实现最大的拉伸强度和断裂伸长 ...

In this article, the structure, mechanical and tribological properties were investigated carefully for the polyamide-6-based composites blended with polyphenylene sulfide (PA6-PPS). It was found...

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.

Namely, the adsorption capacity for PA-TEPA and PA are 0.7 and 0.07 mmol g À1 at 750 mmHg, respectively. It is known that adsorption of CO 2 at room temperature is governed mainly by weak van...
