With increasing the absorbed dose, the contact angles decreased below its pristine value of 70 degree. In the case of proton irradiation, anomalous behavior has been obserbed on the contact angle of water droplets on PADC. The angle reaches to the maximum value of 89 degree from the original value of 70 degree without the exposure at a fluence of 1.0x10^13 ions/cm^2. Similar experiments have been made after gamma irradiations, UV irradiations and the exposure to corona discharge. In oder to evaluate the surface composition, XPS observations were made for PADC, in which X ray irradiation are simultaneously conducted.}, pages = {149--155}, title = {イオン照射したPADC固体飛跡検出器の表面特性評価}, volume = {37}, year = {2011} }
