Bubble Passage: Underwater Superaerophobicity/Superaerophilicity and Unidirectional Bubble Passage Based on the Femtosecond Laser‐Structured Stainless Steel Mesh (Adv. Mater. Interfaces 14/2020). Issue 14 (27th July 2020) - Huo, Jinglan
Abstract : The bubbles' behavior could be controlled by the structured stainless steel mesh fabricated by the combination of one‐step femtosecond laser ablation and chemical modification. The laser‐structured both‐side trinary‐scale rough meshes present superaerophobilciy and superaerophilicity without or with farther fluoroalkylsilane modification, respectively, to realize the bubble's both‐side interception and both‐side passing through. Just one‐side laser ablation and fluoroalkylsilane modification endow the mesh with bubble unidirectional passage property, like a "bubble diode" mesh, which could be used to eliminate and collect the adhered bubbles at the inner wall of a container.
