4Wetting phenomenon is an important phenomenon in nature, and it is related to our daily life closely. Therefore, it is of great practical significance to study wettability surface. Recently, based on the observation and measurement of Nepenthes surface, we realized the liquid or insects will roll down from the surface almost without resistance resulted from the lunate-shaped microstructure and its composite microstructure, which can make the surface possess superhydrophobic properties. Nepenthes Bio-inspired superhydrophobic primary microstructure was fabricated by the two-photon polymerization using femtosecond laser and characterized by developering are still stable after washing observed by Zygo. The lunate are still intact after washing, so the character of hydrophobicity can be maintained. We demonstrate that our approach provide a novel way to fabricate such primary microstructures on the glass using femtosecond laser two-photon polymerization for practical applications in related area.
