Název v původním jazyce

Directing Surface Functions by Inducing Ordered and Irregular Morphologies at Single and Two-tiered Length Scales

Popis výsledku v původním jazyce

Surface topography outlines material’s interaction with its immediate environment. Herein, a series of cost-effective and scalable treatments are used to obtain single scale and two-tiered surfaces with ordered/disordered arrangements of micro and nano features. The applied treatments induced a wide variety of surface features regarding length scale and arrangement. The individual and synergistic contributions of roughness length scale, regularity and hierarchy were analyzed on surface functionalities. The performance of further functionalized and lubricant-infused surfaces was evaluated regarding their interaction with wetting media, as well as tribological and electrochemical resistance. The hierarchical surfaces showed improved wear and corrosion resistance. The prominence of the surface features’ length scale and orderedness varied based on the loading conditions and test environments. Wettability was mainly directed by micro-scale features. Tribology was largely led by the ability of the surfaces in forming a stable low-surface-energy liquid interface. Electrochemical activity was primarily influenced by the synergic barrier effect of the nano-features and the infused lubricant regardless of their arrangement. The results indicate that combining the distinctive and complementary role of micro and nano features can offer the possibility of obtaining versatile multifunctional surfaces with tunable performances based on the expected in-service conditions.
