Fabrication of superhydrophobic binary nanoparticles/PMMA composite coating with reversible switching of adhesion and anticorrosive property

► Superhydrophobic Ag-TiO2-Thiol/PMMA coatings with the capability of UV absorption have been fabricated by spray method. ► The coatings show notable stability in different medium conditions (in acidic (pH = 1) and basic (pH = 14) solution, in artificial seawater (ASTMD1141-98 one week). ► The superhydrophobic coatings are anticorrosive and provide an easy way to protect metal materials effectively.
