本文研究了水黾腿与水面垂直接触时，表面超疏水性对其刺穿力和分离力的影响。研究表明，水黾腿与水平行接触时，刺穿力对接触角不敏感，这引起了人们对水黾腿超疏水性作用的争论，而垂直接触时，刺穿力对接触角非常敏感，这表明表面超疏水性确实对水黾在水面上的自由和安全活动至关重要。
This letter presents a study of the effect of surface superhydrophobicity on piercing force and detaching force of water strider’s leg when it vertically contact with water surface. We showed that in contrast to the parallel contact of the leg with water at which the piercing force is insensitive to the contact angle which raised much debate on the functions of superhydrophobicity of water strider’s leg, the piercing force of the vertical contact is, however, very sensitive to the contact angle, which then suggests the surface superhydrophobicity is indeed crucial for water strider’s free and safe activities on water surface.
