The research team from the School of Materials Science, led by Zhong Minlin and Fan Peixun, has innovatively engineered a chamfer structure on a metal surface and devised a novel technology to directly fabricate this structure on the metal. This design integrates a micron-scale T-shaped structure with surface-grown nanostructures. The micron structure imparts fundamental superhydrophobic and pressure-resistant properties, while the nanostructure functions as an additional energy barrier, enhancing the overall performance. Additionally, the micron structure serves as mechanical support for the nanostructure, offering added protection. Through the collaborative design of the micro-nanostructure, the team fine-tuned the structural parameters to achieve peak performance.
