This paper reports an easy method to prepare transparent superhydrophobic coating by two-step spray-coating method. In order to improve robustness, PDMS oligomers were used to bond the SiO2 nanoparticle/fluoroalkylsilane composite coating to the substrate. The transmittance of coated glass was above 80 % for wavelengths larger than 500 nm. Moreover, the prepared coating exhibited excellent self-cleaning properties in either air or oil environment. Furthermore, this coating retained superhydrophobic properties after three cycles of abrasion test or strong acid/base attack. Therefore, this robust self-cleaning transparent superhydrophobic coating may have a wide range of practical applications in the optical industry.
