The acidic solution of NA and resorcinol was irradiated by gamma-rays with 1200-1800 Gy dose, then was heated to 60 degrees C for at least 16hr to form transparent sol-gel. The translucent aerogel can be obtained from the sol-gel with CO2 as supercritical fluid. Synthetic conditions (e.g. acidity of the solution, ratio of NA to resorcinol) are discussed.展开更多
