|Provided are superhydrophobic coatings, devices and articles including
superhydrophobic coatings, and methods for preparing the superhydrophobic
coatings. The exemplary superhydrophobic device can include a substrate
component and one or more superhydrophobic coatings disposed over the
substrate component, wherein at least one of the one or more
superhydrophobic coatings has a water contact angle of at least about
150.degree. and a contact angle hysteresis of less than about 1.degree..
The one or more superhydrophobic coatings can include an ultra high water
content acid catalyzed polysilicate gel, the polysilicate gel including a
three dimensional network of silica particles having surface functional
groups derivatized with a silylating agent and a plurality of pores.
