Impact of Proton Irradiation on PEEK
Proton irradiation has significant effects on PEEK, particularly in terms of surface microstructure damage and overall structure evolution. When high-energy particles interact with PEEK, they cause ionization and displacement effects that break chemical bonds and create free radicals. These effects induce structural changes in PEEK, leading to surface damage.
The damage caused by proton irradiation is typically limited to the surface of the material. However, it can have a significant impact on the overall structure and performance of PEEK. Understanding the effects of irradiation on PEEK is crucial for assessing its behavior in radiation environments and developing materials with enhanced radiation resistance.
To analyze the microstructure changes of irradiated PEEK, advanced techniques such as synchrotron radiation grazing incidence small angle X-ray scattering (GISAXS) can be employed. GISAXS provides valuable insights into the microstructural modifications that occur as a result of proton irradiation.
