Abstract

The formation mechanism of the mesoporous structures in the silica sol-gel solutions with a structure-directing amphiphilic triblock copolymer was monitored by SANS measurement at various stages during synthesis. The SANS data showed that a long-range liquid crystal-like mesoscopic ordering of the polymer was almost collapsed shortly after being mixed with the prehydrolyzed inorganic silica solution, but it was gradually recovered into the mesostructure with a long range order during evaporating the solvents in the gelation process.
