Biomimetic superhydrophobic surfaces successfully fabricated on high-density polyethylene surfaces by simple heat- and pressure-driven imprinting methods using patterned anodic aluminum oxides as replication templates are reported. On measuring the water contact angle (see figure), it is clearly observed that the nanostructures and microstructures together influence the superhydrophobicity of the polymer surface.
