Polyvinylidene fluoride (PVDF) surface was irradiated and became superhydrophilic by low energy (180 eV) and high flux [Math Processing Error] ion beam. As an ion source, a closed electron Hall drift thruster of [Math Processing Error] outer channel size without grid was adopted. Ar, [Math Processing Error] and [Math Processing Error] were used for source gases. When [Math Processing Error] and [Math Processing Error] reactive gas ion beam were irradiated with the ion fluence of [Math Processing Error] , the wetting angle for deionized water was drastically dropped from [Math Processing Error] , respectively. Surface energy was also increased up to from 44 mN/m to 81 mN/m. Change of chemical component in PVDF surface was analyzed by x-ray photoelectron spectroscopy. Such a great increase of the surface energy was intimately related with the increase of hydrophilic group component in reactive ion irradiated PVDF surfaces. By using an atomic force microscopy, the root-mean-square of surface roughness of ion irradiated PVDF was not much altered compared to that of pristine PVDF.
