The experimental study on water drop’s impacting characteristics on typical wettability of surface of plant leaves (lotus leaf, piemarker, etc) has been taken in this paper, mainly including: the impacting process of water drops on the surface of lotus leaf and piemarker was shot by high-speed camera; the impacting distance of water drops on the surface of lotus leaf with different heights was measured by self-made slope. The results show that: (1) water drop has good wettability on the surface of piemarker, while it can bounce for several times on the surface of lotus leaf; the morphologic change of water drop during impacting process was observed and the energy dissipation process was analyzed; (2) water drop’s impacting distance on different slopes with different dip angles presents linear relation with the dripping distance. This study has laid certain foundation for realizing water drop’s controlled motion on the surface with super hydrophobicity.
