Polymers and fibers

Determine the crystalline/amorphous ratio and crystalline orientation

Many plastic polymers and fibers have some order and can be identified and studied by X-ray diffraction methods. These polymers are, at least in part, crystalline or pseudo-crystalline with partially ordered structures which cause diffraction peaks. In fact, the percent crystallinity in a polymer can be determined by X-ray diffraction methods. This crystalline/amorphous ratio is often related to processing methods and is of much importance in polymer chemistry. Other uses of XRD in plastics and polymers research and production include: determination of unit cell type and lattice parameters, determination of the microstructure, and determination of crystallographic orientation through pole figures.
