Remarkably Simple Achievement of Superhydrophobicity, Superhydrophilicity, Underwater Superoleophobicity, Underwater Superoleophilicity, Underwater Superaerophobicity, and Underwater Superaerophilicity on Femtosecond Laser Ablated PDMS Surfaces

Abstract

Simple achievement of six different super-wettabilities on the femtosecond laser ablated polydimethylsiloxane (PDMS) surface is reported for the first time. Both the experimental and theoretical analysis revealed that underwater oil wettability and underwater bubble’s behavior on a solid surface are closely related to the in-air water wettability of the substrate surface. The original femtosecond laser-induced microstructured PDMS surface showed excellent superhydrophobicity in air and generally became superoleophilic and superaerophilic in water. After further being irradiated by oxygen plasma, the rough PDMS surface switched to superhydrophilic. Underwater superoleophobicity and superaerophobicity could be exhibited when such superhydrophilic PDMS surface was immersed in water. Furthermore, various superhydrophobic-superhydrophilic, underwater superoleophobic-superoleophilic and underwater superaerophobic-superaerophilic hybrid patterns were successfully designed and achieved on the femtosecond laser ablated PDMS surface by subsequent selective oxygen plasma treatment. We believe that the reported preparation principle of superhydrophobic, superhydrophilic, underwater superoleophobic, underwater superoleophilic, underwater superaerophobic, and underwater superaerophilic surfaces will have important guiding significance to researchers and engineers to well control water droplets, oil droplets and the behavior of bubbles on a material surface.
