METHOD FOR PRODUCING MESOPOROUS SILICA STRUCTURE, AND MESOPOROUS SILICA STRUCTURE AND LIQUID CRYSTAL ELEMENT HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a mesoporous silica structure by which the mesoporous silica structure having high porosity and excellent mechanical strength can be produced at a low cost without removing a surfactant by firing a composite body at a high temperature after removing a solvent from the composite body as in a conventional method.;SOLUTION: The mesoporous silica structure is produced successively through (a) a step for forming the composite body by using a solution obtained by adding a surfactant to a silica sol solution, (b) a step for removing a solvent from the composite body, and (c) a step for decomposing and removing the surfactant by subjecting the composite body from which the solvent has been removed to plasma treatment. The plasma treatment is performed preferably in an oxygen atmosphere under a pressure condition of ≤10 Torr.;COPYRIGHT: (C)2005,JPO&NCIPI
