要約(英語): We proposed a large-area double-sided fluorine-free hydrophobic coating on polyethylene terephthalate (PET) surface using atmospheric pressure plasma (APP) irradiation. APP was generated by a dielectric barrier discharge (DBD). In this study, we compared the effect of carrier gases on the hydrophobic coating, observed the chemical structure of the deposited films by X-ray photoelectron spectroscopy (XPS), and calculated input energy density from voltage ampere waveform. The carrier gas, which is helium or argon, carried with silicone water-repellent was supplied to the DBD reactor. The results showed that the irradiated samples become a hydrophobic condition in either case. Compared to the contact angles of both samples, the contact angle using argon plasma became large. In addition, the surface has Si-O bond detected by XPS and confirmed the formation of thin silicone films. It revealed that a large-area double-sided irradiated sample (10×200 mm) became hydrophobic at least 5 seconds when input power density was 7.4 mW/cm2.
