Non-fluorinated superhydrophobic Al7075 aerospace alloy by ps laser processing

Popis výsledku v původním jazyce

The development of non-fluorinated super or ultrahydrophob. aerospace Al alloy(Al7075)surface by las.patterning and high vacuum process for 4h.Lamellar and lotus leaf papillae like struct. covered with nanoscale protrusions are found to be formed depends on the las. fluence and spatial shifts of las. scans.The fresh las. processed hydrophilic surface was vacuum processed to create layer of hydrocarbon to reduce the surface free energy for the wetting property transformation.The analysis of the results shows the synergistic effect of hierarchical structures and dominant presence of non-polar elements is critical for superhydrophobic property.The surface geometry is primarily responsible for the wetting property transformation by entrapping μ-volume of air to generate a composite interface of solid-gas-liquid.Micro and nanoscale(dual scale)surf.struct. are essent. for the durable and consistent superhydrophobic property with high degree of water repellence for bigger vol.of water droplets.
