Controllable morphology transition from vesicular to worm-like to vesicular multilamellar mesoporous silica induced by β-cyclodextrin

Changes in the morphology of mesoporous silica from vesicular to worm-like to vesicular multilamellar were controlled by adding appropriate amounts of β-cyclodextrin to mixed cetyltrimethylammonium bromide/didodecyldimethylammonium bromide surfactant aggregates.
