PA聚酰胺弹性体共聚物xrd曲线为什么没有规律?23度那里似乎有 …
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。
The crystallinity of chemically bonded PA‐PTFE‐oil compounds by …
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.
