Abstract
A method of forming a porous sol gel, including a dried porous sol gel, is provided comprising forming a sol gel from a sol gel-forming composition comprising a silane solution and a catalyst solution; and non-supercritically drying the sol gel to provide a dried porous sol gel having no springback. The dried porous sol gel can include dried macroporous or mesoporous sol gels or dried hybrid aerogels. The materials may contain open or filled pores. Such materials are useful as thermal insulators.
