Han's laser Ultrafast Laser Superhydrophobic Surface Treatment Demonstration
Using ultrafast laser sources, specific microstructures can be formed on metals to achieve superhydrophobic surfaces with sliding angles of less than 10 degrees. Metallic materials with superhydrophobic surface properties can achieve self-cleaning, anti-fouling, and anti-corrosion functions by forming an air cushion, and can be applied in fields such as reducing drag in water pipelines, surface treatment of ships, precision components for consumer electronics, anti-adhesion in medical devices, and improving fuel cell efficiency. Unlike other processes such as etching, laser superhydrophobic treatment can target specific areas, offering a simple and easily controllable process.
