Abstract

A superhydrophobic surface with a static water contact angle (θw) > 150° was created by a simple “dip-coating” method of 60-nm SiO2 nanoparticles onto an amine-terminated (NH2) self-assembled monolayer (SAM) glass/silicon oxide substrate, followed by chemical vapor deposition of a fluorinated adsorbate. For comparison, a close-packed nanoparticle film, formed by convective assembly, gave θw ~120°. The stability of the superhydrophobic coating was enhanced by sintering of the nanoparticles in an O2 environment at high temperature (1100 °C). A sliding angle of <5° indicated the self-cleaning properties of the surface. The dip-coating method can be applied to glass substrates to prepare surfaces that are superhydrophobic and transparent.
