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, Al2O3, SrTiO3, TiN, ZnS, CuO, Ag2O, and Cr2O3) change during it-radiation 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.
