Abstract
A method for synthesizing a hydrophilic graphene-modified polyurethane foam membrane, is described. The method includes functionalizing graphene oxide particles with tartronic acid to form a functionalized product having a hydrophilic functional group; and reacting the functionalized product with a polyurethane to form the hydrophilic graphene-modified polyurethane foam membrane. The hydrophilic graphene-modified polyurethane foam membrane has a water adsorption capacity of at least 20 g/g. The hydrophilic graphene-modified polyurethane foam membrane is adapted for a use selected from the use group consisting of oil and water separation, water treatment, desalination, and pharmaceutical filtration.
