Abstract

The manipulation of underwater bubble using the superwetting surface is crucial for industrial and scientific research. However, most of the superwetting surfaces are not able to achieve precise control for underwater bubble transportation. Here, a new method was proposed to construct a superaerophobic wedge pattern on superaerophilic wedge surface for precise underwater bubble transportation. The pattern was fabricated on the aluminum plate for underwater bubble transportation by the secondary laser etching and fluoroalkylsilane modification techniques. In this study, the wedge angle and the length of superaerophobic wedge pattern were investigated for the underwater bubble transportation on the superaerophilic wedge surface, and the results showed that the transportation distance of underwater bubbles could be precisely controlled by adjusting the wedge angle and the length of superhydrophobic wedge pattern.
