Abstract
Herein, the transparent omniphobic coating on glass slides was fabricated by using three different colloidal dispersions as sacrificial templates for a silica sol to make nano-scale surface roughness. These surface structures were further functionalized with a long chain fluorinated silane. These coatings showed a stable repellency to both water and low-surface tension liquids with the maximum contact angle of 156° to water and of about 130° to corn and paraffin oils. The prepared glass slides presented very high transparency with a light transmittance of about 92–98%. The coated surfaces were stable up to 400 °C and represented a good resistance under corrosive conditions by immersing 24 h in aqueous solutions of H2SO4 (pH 2) and KOH (pH 14).
