摘要：

Stable superhydrophobic silver films were fabricated on glass substrates by using the silver mirror reaction. The water contact angle (CA) on the obtained silver surface was 154 degrees, and a water droplet could easily roll off. Both the CA and surface roughness could be tailored by altering the initial silver ion concentration. The movement of a superhydrophobic ball on the surface of water was also investigated and compared with that of a superhydrophilic ball. The results suggested that the superhydrophobic coating on the ball repulsed water and provided extra supporting force, leading to a faster movement on the surface of water. We hope that our findings would improve the understanding of superhydrophobic properties and be useful in further research on drag-reducing materials.
