Ravindra Deshpande, Douglas M Smith, C Jeffrey Brinker: Preparation of high porosity xerogels by chemical surface modification.. October 15, 1996: US05565142 (72 worldwide citation)

This invention provides an extremely porous xerogel dried at vacuum-to-below supercritical pressures but having the properties of aerogels which are typically dried at supercritical pressures. This is done by reacting the internal pore surface of the wet gel with organic substances in order to chang ...
