Abstract
Low density, buoyant materials, in particular hydrophobic aerogels, may be used to absorb hydrophobic liquids. The materials are adapted to float on aqueous solutions and can absorb oils or other hydrophobic liquids from the surface of the solution without absorbing appreciable amounts of the aqueous solution. Methods for creating and using the materials are disclosed.
