Abstract
Embodiments are directed to compositions comprising (i) amphiphilic block copolymer, (ii) resin material; and amine modified graphene oxide; where the composition shows a synergic effect in critical strain energy release rate (Glc) value versus predicted value calculated by adding (i) the Glc value for neat resin material, plus (ii) the difference in Glc found when adding the amphiphilic block copolymer to the resin material versus the neat resin material, plus (iii) the difference in Glc found when adding the amine modified graphene oxide to the resin material versus the neat resin material.
