A facile approach for TiO2-based superhydrophobic–superhydrophilic patterns by UV or solar irradiation without a photomask

Abstract

A novel and facile approach to produce TiO₂-based superhydrophobic–superhydrophilic patterns by UV or solar irradiation without a photomask is presented. The fabricated superhydrophobic–superhydrophilic patterns with excellent mechanical properties have long lifetimes in outdoor applications or other UV environments because of a self-supply of low surface tension material.
