Transparent durable superhydrophobic ceramic coating

机译:透明耐用的超疏水陶瓷涂料

摘要

A superhydrophobic ceramic coating that is transparent and durable includes a dispersion of a multiplicity of silica nanoparticles stacked to form a topography that is rough that is infused with and conformally coated with a sol-gel glass matrix that has a fluoroalkyl silane or an alkyl silane monolayer on the surface of the coating. The silica nanoparticles do not scatter light to a large extent as they are sufficiently small and free of aggregation. The sol-gel glass is formed from a trialkoxysilane precursor and applied to the stacked silica nanoparticles to retain the rough topography of the deposited nanoparticles.
