The examination of Bragg peaks scattered to broad angles, which are brought on by sub-nanometer-sized structures according to Bragg’s law, is known as wide-angle X-ray scattering (WAXS) or wide-angle X-ray diffraction (WAXD).
It is an X-ray diffraction technique that is frequently used to gather a variety of data on crystalline materials. The term WAXS is frequently used in the polymer sciences to distinguish it from SAXS, but many researchers that use “WAXS” would refer to the observations as crystallography or Bragg/X-ray/powder diffraction.
Similar to small-angle X-ray scattering (SAXS), wide-angle X-ray scattering (WAXS) probes lower length scales due to the increased angle between the sample and detector.
To extract information, samples need to be more structured/crystalline. The sample is farther away from the detector in a specialised SAXS device in order to improve angular resolution.
By adding a beamstop/knife edge, the majority of diffractometers may be used to conduct both WAXS and limited SAXS in a single run (small- and wide-angle scattering, or SWAXS).
The Global wide angle X-ray scattering (WAXS) market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Using the WAXS approach, polymer sample samples’ levels of crystallinity are evaluated. Also, it can be used to figure out a film’s chemical makeup or phase composition, texture preferred alignment of crystallites, crystallite size, and whether or not film tension is present.
The sample is scanned in an X-ray goniometer with a large field of view, as in previous diffraction techniques, and the scattering intensity is shown as a function of the 2 angle.
According to the number of electrons (atoms) in the hypothetical planes, the intensity of the d-space pattern increases linearly.
Every crystalline solid has a distinct pattern of d-spacings sometimes referred to as the powder pattern, which serves as the solid’s fingerprint. The pattern of d-spacings in a solid can be used to distinguish between solids with the same chemical make-up but different phases.
