Polyhedral Oligomeric Silsesquioxane (POSS) has emerged as a new class of organic/inorganic hybrid material. POSS is nanostructure with the empirical formula RSiO1.5, where R may be a hydrogen atom or organic functional group, alkyl, alkylene, acrylate, hydroxy or epoxide unit. Theses functional groups could react chemically with the polymer matrix. In this study, we prepared organic-inorganic hybrid PU network using diol-functionalized POSS. The incorporation of POSS units into polymer may improve the properties such as mechanical strength, thermostability, oxidative resistance and hydrophobic. The hybrids materials were characterized using Nuclear Magnetic Resonance(NMR), Fourier Transform Infrared spectroscopy (FT-IR) and Differential Scanning Calorimeter(DSC). |
