A smart rough PTFE surface with switchable underwater bubble's wettability is fabricated by one‐step femtosecond laser ablation. The reversible transition on the hierarchical PTFE surface between underwater superaerophilicity and underwater superaerophobicity can be realized through alternate vacuum‐pumping and drying treatment for many times. The transition property is used to realize the function of bubble “locating capture” and selective bubble passage. More details can be found in article number 1900262 by Jiale Yong, Feng Chen, and co‐workers.
