Air Bubble Contro: Trapped Air‐Induced Reversible Transition between Underwater Superaerophilicity and Superaerophobicity on the Femtosecond Laser‐Ablated Superhydrophobic PTFE Surfaces (Adv. Mater. Interfaces 17/2019). Issue 17 (6th September 2019) - Huo, Jinglan
Abstract : 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.
