“…Moreover, the ion beam only affects a thin surface, reaching a depth of approximately 100 nm; thus, this process alleviates concerns regarding the structural integrity and maintains the properties of the substrates. Furthermore, although several studies of irradiation have been performed for polyimide using ion beam irradiation, − to the best of our best knowledge, no study has yet revealed the transient superhydrophilic behavior.…”

Polyimide is commonly used as a substrate for flexible electronic devices because of its excellent thermal, physical, and electrical properties. To enhance the adhesion between substrates and electrodes, it is necessary to improve the hydrophilic properties of the polyimide. Various surface treatments, such as plasma treatment, laser ablation, and ultraviolet treatments, have been applied for this purpose. In this study, we demonstrated that Cu and Ti ion beam irradiation can temporarily create a superhydrophilic surface on polyimide after irradiation. When Cu or Ti ions bombarded the polyimide, the contact angle changed systematically with the beam current density and over time. We present atomic force microscopy (AFM) data for polyimide irradiated with Cu and Ti ions at different beam current densities and discuss the possible mechanisms behind the changes in the contact angle.
