A particle containing a hydrophobic region and a hydrophilic region, products containing the same, a process of making the same, and uses thereof are described. A process of making the particle is also described wherein UV /
Ozone techniques can be used to control the depth of organics removal from a porous hydrophobic particle such as an
aerogel. The particles can be used in a variety of applications, such as a
monolith, a building block, an optical
waveguide, a
blanket, a matting agent, a structural composite panel, a glass-
fiber reinforced panel, a window, a separation wall, a composite wall, a temperature insulation panel, a sound insulation panel, a
moisture resistant article, a
syntactic foam, or any product of manufacture containing the particles.
