X-ray Diffraction Wide Angle X-Ray Diffraction or WAXD is a widely used technique to determine the crystalline structure of polymers. This technique specifically refers to the analysis of Bragg peaks scattered to wide angles, which (by Bragg's law) implies that they are caused by sub-nanometer-sized structures. The diffraction pattern generated allows researchers to determine phase composition and, hence, this technique can also be used for determination of percentage crystallinity of a sample. According to this method the sample is scanned in a wide-angle X-ray goniometer, and the scattering intensity is plotted as a function of the 2θ angle. X-ray diffraction is a non destructive method of characterization of solid materials. When X-rays are directed in solids they will scatter in predictable patterns based upon the internal structure of the solid. A crystalline solid consists of regularly spaced atoms (electrons) that can be described by imaginary planes. The distance between these planes is called the d-spacing. Every crystalline solid will have a unique pattern of d-spacings, which is an identity for that solid. In fact solids with the same chemical composition but different phases can be identified by their pattern of d-spacings.
Preparation Guidelines Samples : All solid samples in powder form will be acceptable (175 mg.) for XRD.
