Abstract

The present work deals with a mechanistic study of mesoporous materials formation using a fluorinated surfactant. Pore size of materials has been enlarged either by increasing the weight percent of surfactant in water or by incorporating perfluorodecalin (PFD) as swelling agent. A change in micelle shape is assumed to explain the variation of the pore diameter with surfactant concentration. Phase behavior of surfactant/water system and evolution with PFD loading have been studied. Determination of hexagonal liquid crystal parameters and characterization of the recovered materials have been investigated. This work also shows that the pore size enlargement is related to PFD incorporation in hexagonal liquid crystal (H1) and not in micelles (L1).
