Amino acid subject to attack by free radicals can be grafted onto the surface of a preformed polymer by treating the surface with a highly basic solution of the molecules to be grafted. Using this method, a preformed poly(vinylidene fluoride) surface can be rendered hydrophilic by subjecting the surface to a highly basic solution of glycine.
