NOVELTY - Preparing high strength epoxy resin involves mixing silane coated silica, cross linking agent having an isocyanate terminal group and graphene oxide to obtain silica graphene oxide complex which is dispersed in an epoxy resin. USE - Method for preparing high strength epoxy resin (claimed). ADVANTAGE - The method enables to prepare high strength epoxy resin with improved thermal stability, acid resistance, solvent resistance and excellent mechanical properties.
