a Double-scale periodical microcones with dense nanoparticles (denoted as MCNP) by laser. b Single-scale periodical microcones (SMC) by laser. c Double-scale random microbumps with dense nanoparticles (MBNP) by laser. d Irregular micro-nanostructure by chemical etching (IMN). SEM images with different magnifications e of MCNP, f of SMC, g of MBNP, and h of IMN. Scale bars are marked. i Surface roughness of four surfaces. j Contact angles (CA) and sliding angles of four surfaces at room temperature (15 °C and a humidity of 20%). Contact angles of four surfaces are marked. Data are mean ± s.d. from at least three independent measurements.
