Liquid manipulation is essential for daily life and modern industry, it widely used in various fields, including seawater desalination, microfluidic robots, biomedical engineering. Nevertheless, the current research focuses on of individual droplets. There are a few projects water film management. Here, we proposed facile method wind-triggered self-sculpturing based heterogeneous wettability surface, which achieved by femtosecond laser direct writing technology deposition. Under conditions airflow velocities thicknesses, three distinct behaviors were analyzed. As result, when thickness lower than 4.9 mm, self-sculpture process will occur until whole superhydrophobic surface dewetting. Four potential applications demonstrated, encryption, oil containers, reconfigurable patterning, self-splitting devices. This work provides new approach manipulating fluid control

Published: Aug. 24, 2024

Polymer-based textiles have a major impact on human well-being, as they provide the desired functional protection and aesthetic comfort when worn. However, natural synthetic polymer-based can also pose serious health risks, are surfaces that allow adhesion of various bacteria, including pathogenic bacteria. To minimise these problems, antibacterial chemical treatments generally applicable in case textiles. to avoid use potentially toxic chemicals, sustainable approaches require customised design non-adhesive textiles, considering their chemical, physicochemical, constructional, textural properties. Before designing, several articles required gain sufficient knowledge described object. Despite urgent need combat bacteria (on textiles), which global risk, only few review been published address bacterial context superhydrophobic textile materials, while one article holistically addresses factors influence this phenomenon. The aim is expand insufficient about basis theoretical findings real examples through high degree structuring, simplification, holistic consideration, visualization.
