Abstract

We observed that hard X-ray irradiation modifies the wettability of a variety of inorganic materials. The smooth surfaces of all tested inorganic materials (ZnO, p-Si, Al ₂O ₃, SrTiO ₃, TiN, ZnS, CuO, Ag ₂O, and Cr ₂O ₃) change during irradiation to a state of superhydrophilic wettability, and such changes are explained by the accumulation of positive surface charges by photoelectron emission. The initial wettability state is re-established within several minutes of storage in deionized water.
