Single-step formation of superhydrophobic surfaces using photobase-catalyzed sol-gel process

摘要

Superhydrophobic surfaces with a water contact angle greater than 150 degrees were prepared by one-step photo-induced crosslinking of a tetraethyl-orthosilicate and a fluorinated organosilane mixture using an efficient photobase catalytic system. Infrared spectroscopy and electron microscopy techniques enabled to investigate the alkoxysilane condensation and the observation of nano/microparticles.
