Polymer xray
Web(2013). Small-angle X-ray scattering (SAXS) is normally employed to probe the polymer structures, such as the radius of gyration (R g) and thickness of the lamellar crystal for which the dimensions are in the nanometer range. However, it is important to note that the key to the X-ray scattering techniques is the quality of the X-ray source. WebApr 14, 2014 · Enhanced Polymer Reaction. Because of x-ray sterilization’s very short exposure times, its radiation effects on materials—especially polymers—are often measurably less than those caused by gamma processing. In fact, the effects of x-ray processing are very similar to those associated with E-beam sterilization.
