Fabrication of robust and stable superhydrophobic surface by a convenient, low-cost and efficient laser marking approach

Facile Fabrication, Structures, and Properties of Laser‐Marked Polyacrylamide/Bi2O3 Hydrogels

“…The change in the surface properties is mainly due to the formation of a number of small holes on the laser‐marked surface and the production of Bi metal on the surface layer. Our explanation is supported by the results reported by Tang et al They developed a facile laser‐marking method for fabricating a superhydrophobic surface on an aluminum alloy. Their results showed that the formation of a rough surface with irregular protrusions induced by laser irradiation contributed significantly to the generation of excellent superhydrophobicity.…”

Hybrid Laser Ablation and Chemical Modification for Fast Fabrication of Bio-inspired Super-hydrophobic Surface with Excellent Self-cleaning, Stability and Corrosion Resistance

“…To further investigate the performance of the fabricated super-hydrophobic surface, the bouncing experiments were carried out using a high-speed camera. be noticed during the whole shock (Video 2), implying that the adhesive force between the droplet and the as-prepared surface was extremely low and could be ignored [32] . On the contrary, the water droplet will firmly stick on the bare aluminum surface and cannot rebound off the surface due to the high adhesive force, as shown in Fig.…”

“…Therefore, the special hierarchical rough surface texture can generate large space in which the air could be trapped, resulting in the suspension of liquid droplet on the fabricated sample. The high WCA can be described by the Cassie-Baxter equation [32][33][34]…”

Preparation of hierarchically structured PCL superhydrophobic membrane via alternate electrospinning/electrospraying techniques

“…In order to create hierarchical structure with more rough surfaces, a number of methods are developed to manufacture superhydrophobic surfaces, including templates, chemical vapor deposition, laser irradiation, and so forth . Although these methods are effective, they require high cost of machinery and precise conditions.…”
