Observation of orientation state of polypropylene film products by 2D-GI-WAXS measurement

AppNote B-XRD2032: Observation of orientation state of polypropylene film products by 2D-GI-WAXS measurement

Background

The grazing-incidence wide-angle X-ray scattering (GI-WAXS) technique is often employed for the measurement of ultrathin film specimens since their very weak signals can be effectively observed. GI-WAXS can be applied to materials that cannot be evaluated by transmission WAXS, such as thin film on a substrate or a polymer film with metal deposition on the back surface. The combination of a 2D-SAXS/WAXS attachment with an aperture slit and a 2D detector allows the acquisition of clearly resolved 2D diffracted images by a general X-ray diffractometer with a line-shaped incident beam.
