METHOD FOR PRODUCING AEROGEL, AEROGEL, AEROGEL BLOCK, AND POLYSILOXANE COMPOUND

摘要

The present invention relates to a method for producing an aerogel provided with a sol generation step for generating a sol containing a silicon compound or a hydrolysis product of a silicon compound, a wet gel generation step for gelling the sol to obtain a wet gel, and a drying step for drying the wet gel to obtain an aerogel, the silicon compound including a polysiloxane compound having a structure represented by general formula (S). [In formula (S), R^1s each independently represent an alkyl group or aryl group, R^2s each independently represent an alkyl group, aryl group, or hydrogen, ns represents an integer of 2 or higher, ms represents an integer of 2 or higher, and ls represents an integer of 2 or higher.]
