Controllable fabrication of organosilane nano-architectured surfaces with tunable wettability

► The organosilane nano-architectured surfaces were controllable fabricated on glass substrates by liquid phase method. ► The surfaces prepared by through hydrolysis and polycondensation of trichlorosilanes in toluene solution with trace water. ► The alkyl length of trichlorosilanes was found to have critical influence on the surface nano-architectures and corresponding wettability. ► These behaviors originate from the competition between steric effect and alkyl hydrophobicity.
