Design and fabrication of a superhydrophobic glass surface with micro-network of nanopillars

► Transparent superhydrophobic glass surface with a micro-network of nanopillars.Nanopillars are fabricated via colloidal lithography and plasma etching. ► Mechanical robustness of network of nanopillars is confirmed through a finger rubbing test. ► Size-dependent contact angle equation is proposed at high contact angle (>135°) and Bond number ≪ 1. ► Furmidge's sliding angle equation is modified just considering static contact angle.
