An electrically and ionically conductive porous material including a
thermoplastic binder and one or more of anion exchange moieties or cation
exchange moieties or mixtures thereof and/or one or more of a protein
capture resin and an electrically conductive material. The thermoplastic
binder immobilizes the moieties with respect to each other but does not
substantially coat the moieties and forms the electrically conductive
porous material. A wafer of the material and a method of making the
material and wafer are disclosed.
