Notes:
Epoxy-cyanate (EP-CE) ester composites containing the inorganic-organic hybridpolyhedral oligomeric silsesquioxane (POSS) octaisobutyl(T8)-POSS (oib-POSS) were prepared.These EP-CE/POSS composites were characterized by gelation characteristics, transmissionelection microscopy (TEM), X-ray diffraction (XRD), differential scanning calorimetry (DSC),thermal gravimetric analyses (TGA) and dynamic mechanical analysis (DMTA). The glasstransition temperature (Tg) and thermal decomposition temperature (Tdec) of composites increasedcompared with the neat epoxy-cyanate ester with the increment of POSS content. Additionally, allthe EP-CE/POSS composites exhibited higher storage modulus (E’) values (temperature〉Tg) thanthe pure resins. The loss factor peak intensities decreased as the weight percentage of POSSincreases. TEM and XRD showed that phase-separated aggregates of POSS were found in matrix,because POSS did not react with the resin
