Preparation of a biomimetic superomniphobic hierarchical structure and analysis of droplet wettability

Abstract: In this study, a bioinspired hierarchical structure was formed with superomniphobicity on a 7075 aluminium alloy using laser ablation. The morphology and wetting characteristics of the biomimetic sample surface were characterised using scanning electron microscopy, laser confocal microscopy, and contact angle measurements. The effect of the liquid properties and surface structures on the rolling behaviour was investigated. The results suggest that the fabricated biomimetic sample surface was a hierarchical str… Show more

“…To improve drag reduction and wear resistance, dimpled textures that mimic those found in nature (e.g. dung beetles, scarabs, weevils, and star beetles) are an effective approach [2, 3]. In this approach, solid lubricants, such as polytetrafluoroethylene (PTFE), MoS 2 , and graphite, are filled into dimples on the surface of friction pairs to achieve good antifriction performance of the solid lubricants and friction and wear performance of the textured surface.…”
