Slow Positron Study on ZnO/Silicone Under 90keV Proton Irradiation

摘要：

The degradation of ZnO/Silicone coating system owing to 90keV proton irradiation, varied from 5×1014cm to 1×1016cm-2, is studied using slow positron beam. Effective diffusion length calculated by VEPFIT shows a dramatically break in the dose of 1×1015cm-2.It seems to be caused by the increase of cross-link density and decrease of free-volume during the proton irradiation, which consists with the conclusion of other groups. Furthermore, positron has shown a satisfying sensitivity in detecting the defect of nano-scale on ZnO/Silicone system.
