Abstract: Surface treatment of a poly(ethylene naphthalate) (PEN) film by atmospheric pulsed microplasma with humid Ar gas was experimentally investigated. A Marx generator with metal--oxide--semiconductor field-effect transistor (MOSFET) switches that generates negative pulses was used for generating microplasma. Hydrophilization was estimated by measuring contact angle before and after the microplasma surface treatment by a remote process. The initial contact angle was about 76°. The minimum contact angle of about 20° was obtained after a treatment, a discharge voltage of $-1.3$ kV negative pulse, a frequency of 24 kHz, a gas relative humidity of about 60%. Analysis by X-ray photoelectron spectroscopy (XPS) showed a decrease in the C 1s peak corresponding to the C--H bond or C--C bond, and increases in the O 1s peaks corresponding to the C=O bond or O--H bond.
