Outline of Final Research Achievements

In this study, it was demonstrated that ammonium hexafluorosilicate can be effectively formed as the by-product during the encapsulation of low molecular weight aromatic compounds into the fluoroalkyl end-capped oligomers/silica nanocomposite cores, and the ammonium hexafluorosilicate was also important as a factor which may exhibit the nonflammable characteristic toward these aromatic compounds. In addition, the low molecular weight aromatic compounds, which were encapsulated into the calcium fluoride nanocomposite cores, can afford the nonflammable characteristic. In this way, this study shows that the hexafluorosilicate anions and the calcium fluorides are very important inorganic materials for imparting the nonflammable behavior for a variety of organic compounds.
