Polymer materials have a wide range of applications in all aspects of today's society, from packaging materials to aerospace engineering, and different properties of polymer materials for different purposes. The Degree of Crystallinity (DOC) is the main index that affects the properties of polymer materials, and the change of crystallinity will affect various properties of polymer materials, such as mechanical properties, thermal properties, density and optical properties. Therefore, controlling the crystallinity of polymer materials is a key factor in materials engineering.
Generally, the methods for measuring crystallinity include density method, calorimetry, NMR, IR and XRD, etc., among which X-ray diffraction method is recognized, has a clear instrument and a more widely used method, which can analyze polymer structure information more comprehensively and intuitively. The common methods used to determine the crystallinity of polymers by X-ray diffraction are mapping, regression line, Ruland and X-ray diffraction curve partial peak fitting.
FRINGE SH1827 plastic crystallinity analyzer mainly uses X-ray diffraction technology and full spectrum fitting method to calculate the crystallinity analysis of polymer material samples. It has the advantages of simple operation, excellent resolution and good repeatability.
