Graphene has received much attention recently as a material for improvement of polymeric nanocomposite properties due to its outstanding strength, stiffness, high thermal and electrical conductivity and gas impermeability. Recent investigations of cyanate ester resins as high temperature resin materials for space and propulsion applications have brought attention to the need for high temperature composite materials with improved stiffness, strength, hotwet performance and high maximum use temperatures. The incorporation of grapheme in polycyanurate matrices should result in composites with improvement on one or all of these properties. Additionally, different forms of grapheme, such as grapheme oxide, offer the potential of improved interaction between filler and polycyanurate matrix. Graphene oxide was prepared from graphite and dispersed in commercially available bisphenol E dicyanate LECy in 1, 2 and 5 wt loadings. The resulting properties of oxygen functionalized grapheme sheets dispersed in polycyanurate matrix will be presented.
