Abstract
The method of the present invention includes grafting a glycidyl alkylene trialkoxy silane to a novolac phenolic resin in an organic solvent to form a modified novolac phenolic resin; mixing a tetralkoxy silane, an acid and water with the resulting organic solution containing the modified novolac phenolic resin, wherein hydrolysis and condensation reactions are carried out to form a —Si—O—Si— bonding; adding a curing agent for novolac phenolic resin to the resulting reaction mixture; evaporating the organic solvent and acid from the resulting mixture and heating the resulting mixture to form a novolac phenolic resin/silica hybrid organic-inorganic nanocomposite.
