Abstract: In this paper, we report one novel kind of organic inorganic mesoporous hybrid from octa-anionic polyhedral oligomeric silsesquioxanes (PUSS) and cationic surfactant. The mesoporous hybrid was achieved by two steps: first, lamellar precursor made of PUSS and surfactant was prepared by template-directed synthesis; then mesoporous structure was obtained via the reformation of lamellar precursor under hydrothermal treatment. According to our experimental results (XRD, TEM and SEM), the lamellar-to-hexagonal mesophase transformation process and its mechanism was suggested. The thermal stability and degradation behavior of the mesoporous hybrid was also discussed based on TGA curves obtained under nitrogen atmosphere. (C) 2010 Elsevier Inc. All rights reserved.
