A superhydrophobic surface with a static water contact angle (qw) > 150o 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. The stability of the superhydrophobic coating was enhanced by sintering of the nanoparticles in an O2 environment at high temperature (1100 oC). The dip-coating method can be applied to glass substrates to prepare surfaces that are superhydrophobic and transparent.
