Abstract: The present disclosure describes functional membranes and a method for making a functional membrane. The method includes providing a porous substrate, applying the at least one graftable species to the porous substrate, and treating the coated porous substrate with electron beam radiation to provide a functionalized membrane. The method includes forming a functionalized membrane comprising a gradient of grafted species attached to the porous substrate.
