TAMON,* H. ISHIZAKA, M. MIKAMI and M. OKAZAKI Department of Chemical Engineering, Kyoto University, Kyoto 606-01, Japan (Received 10 September 1996; accepted in revised form 13 December 1996) Abstract-Organic aerogels were synthesized via the sol-gel polycondensation of resorcinol with formalde- hyde in a slightly basic aqueous solution and followed by supercritical drying with carbon dioxide. As a result of characterization by nitrogen adsorption, the resorcinol-formaldehyde (RF) aerogels were mesoporous materials with high surface areas and had few micropores. The surface area of the RF
