초록
In this study, a facile method to fabricate superhydrophobic surfaces on perfluoroalkoxy(PFA) films using ion implantation was developed. PFA films were implanted at 100 keV witha fluence ranging from 4×1016 to 7×1016 ions cm-2. The surface properties of the implanted filmswere investigated in terms of their surface morphology, wettability, and chemical composition. Asthe fluence increased to 6×1016 ions cm-2, the surface morphology and surface roughness of thePFA films were dramatically changed. The PFA surface implanted at a fluence of 6×1016 ionscm-2 showed a maximum contact angle (CA) of 157.1, while the control CA of the smooth PFAsurface was 103.6. Thus, the superhydrophobic surface was successfully fabricated by ion implantation.
