| Abstract: Provided are polymer-aerogel composite coatings, devices and articles
including polymer-aerogel composite coatings, and methods for preparing
the polymer-aerogel composite. The exemplary article can include a
surface, wherein the surface includes at least one region and a
polymer-aerogel composite coating disposed over the at least one region,
wherein the polymer-aerogel composite coating has a water contact angle
of at least about 140.degree. and a contact angle hysteresis of less than
about 1.degree.. The polymer-aerogel composite coating can include a
polymer and an ultra high water content catalyzed polysilicate aerogel,
the polysilicate aerogel including a three dimensional network of silica
particles having surface functional groups derivatized with a silylating
agent and a plurality of pores. |
