With the development of energy exploitation and drug researching, people pay more attention on underwater gas collection. Switchable bubble wettability surfaces play an important role in these areas. In this paper, a fast, flexible and efficient switchable bubble wettability copper surface processing method is reported. It is using spatial light modulated femtosecond laser sputtering and ablation, and its processing efficiency has increased several times. The laser treated copper mesh surfaces not only show reversible switching ability between underwater (super-)aerophilicity and superaerophobicity, but also can be cycled many time. Therefore, the as-prepared surface can control bubbles to pass through or block by switching wetting property. Finally, we demonstrated the underwater superaerophobic characteristic of the as-prepared copper mesh was used for gas collection and the gas intrusion pressure of the prepared copper mesh was studied theoretically and experimentally.

随着能源开发和药物研究的发展，人们越来越重视水下气体的收集。可切换的气泡润湿性表面在这些区域中起着重要的作用。本文报道了一种快速，灵活，高效的可切换气泡润湿性铜表面处理方法。它使用空间光调制飞秒激光溅射和烧蚀，其处理效率提高了数倍。激光处理过的铜网表面不仅显示出在水下（超）好氧性和超好氧性之间可逆的转换能力，而且还可以循环多次。因此，准备好的表面可以通过切换润湿性来控制气泡通过或阻塞。最后，
