The layered structure of polymer materials varies in length. Therefore, taking crystalline polymers as an example, it is required to evaluate the structure of polymers of various length layered structures, such as: from micron spherulites to sub-nano-level intercrystalline segregation and so on. By integrating various polymer structure evaluation techniques, different layer structures of polymers can be analyzed.
Structural analysis using cash radiation equipment
The structure and characteristics of polymer materials vary significantly with different production conditions, engineering processes, and use environments. For example, in film stretching, the structure of the film under tension is very different during and after stretching.
It is possible to evaluate whether the in-situ structure changes in the actual engineering process are ideal, but because these structural changes occur during the process, special equipment is required. Using advanced synchrotron radiation equipment, powerful X-ray function, can observe the structural changes in the film stretching process, and can find that the PVA film changes continuously, from a layered structure to a fibrous structure.
