Abstract:
1. A device incorporating a thin wafer not less than about 1 mm in thickness of an electrically and ionically conductive porous material made by the method of introducing into a mold a mixture of (a) a thermoplastic binder,(b) one or more ion exchange moieties selected from the group consisting of an anion exchange moiety, a cation exchange moiety, and mixtures thereof, (c) an electrically conductive material; and optionally, (d) one or more of a protein capture resin, subjecting the mixture to temperatures in the range of from about 60° C. to about 170° C. at pressures in the range of from about 0 to about 500 psig for a time in the range of from about 1 to about 240 minutes to form the thin wafer of electrically and ionically conductive porous material, and removing the thin wafer from the mold; wherein said thermoplastic binder immobilizes the moieties with respect to each other but does not substantially coat the moieties.
