  • Publication number: 20070154379
    Abstract: Silica aerogels that are controlled in pore diameter and pore diameter distribution can be produced as follows: a surfactant is dissolved in an acidic aqueous solution; a silicon compound having a hydrolysable functional group and a hydrophobic functional group is added thereto, so that a hydrolysis reaction is carried out to yield a gel; and after the gel is solidified, the gel is dried supercritically. Preferably, the surfactant is one selected from the group consisting of a nonionic surfactant, a cationic surfactant, and an anionic surfactant, or a mixture of at least two of them.

  • Publication number: 20050285290
    Abstract: In a method of manufacturing an organic/inorganic hybrid porous material containing both mesopores and macropores, a homogenous solution is prepared where a water-soluble polymer or amphipathic material as a phase separation induction element is dissolved in an aqueous solution containing sol-gel reaction catalyst elements, and a continuous 3-dimensional mesh-structured gel including a solvent-rich phase is formed. The gel is immersed in an aqueous solution containing a compound generating ammonia via hydrolysis and curing under hydrothermal conditions by heating in a closed state to form macropores by drying the gel and to evaporate the solvent from the solvent rich phase. Mesopores is formed in the skeletal phase by removing the phase separation induction elements from the gel after drying via thermolysis or extraction.
