| Abstract: | Linear isocyanate-terminated poly(urethane-imide)(PUI) with combination of the advantages of polyurethane and polyimide was directly synthesized by the reaction between polyurethane prepolymer and pyromellictic dianhydride.Then,polyhedral oligomeric silsesquioxane(POSS) and PUI were incorporated into the epoxy resin(EP) to prepare a series of EP/PUI/POSS organic-inorganic nanocomposites for the purpose of simultaneously improving the heat-resistance and toughness of the epoxy resin.Their thermal degradation... |
