Abstract: Lamellar organic-inorganic hybrid was prepared by ion-exchange reaction of octa(gamma-chloroammoniumpropyl) polyhedral oligomeric silsesquioxanes (OCAP-POSS) and anionic surfactant. Lamellar structure can be expected by self-organization for the different compatibility between its inorganic parts (silicon-oxygen cages) and organic parts (organic substituents of OCAP-POSS and DBSS alkyl chain). The composition and structure of the hybrid were characterized by FT-M, elemental analysis, high-resolution TEM and SEM, which shows that all the chlorine ions in OCAP-POSS are replaced by surfactant organic chains and a two-dimensional multilayered structure is formed. The thermal degradation behavior of the hybrid was investigated by TGA in nitrogen atmosphere. (c) 2006 Elsevier B.V. All rights reserved.
