Ultraviolet-Durable Superhydrophobic Nanocomposite Thin Films Based on Cobalt Stearate-Coated TiO₂ Nanoparticles Combined with Polymethylhydrosiloxane.

It is extremely significant to develop UV-durable superhydrophobic thin films especially for painting the exterior surfaces such as building walls which are normally exposed to the UV light directly from the sun. 35 A comparative UV degradation study has been performed on two superhydrophobic thin films prepared by a sol–gel process using (i) TiO 2 nanoparticles and PMHS (coded as PMHS/TiO 2 ) and (ii) CoSA-modified TiO 2 nanoparticles and PMHS (coded as PMHS/TiO 2 @CoSA) in our UV chamber developed in-house.
