Patent ID: 8420729

Claim:
A method for preparing a nanohybrid resin of carbon nanomaterials and phenolic resin to be applied in carbon containing refractories and in carbon-carbon composites, wherein said method comprises the steps of a) mixing and ultrasonicating said carbon nanomaterial in an organic solvent to obtain a colloidal dispersion of carbon nanomaterial wherein said carbon nanomaterial comprises carbon black and carbon nano tube and said organic solvent comprises ethylene glycol and/or 1,2 propanediol; b) adding and mixing 10-15% by weight of the colloidal dispersion of said carbon nanomaterial to phenolic resin to obtain said nanohybrid resin, wherein said carbon nanomaterials act as a graphitizing agent during conversion of the resin to a graphite phase; and d) Heating or firing said nanohybrid resin at 1100° C. to obtain a residual carbon containing refractory.
