NOVELTY - The method of forming an electrically and ionically conductive flexible and porous material, comprises subjecting a mixture of a thermoplastic binder (25-70 wt.%) and anion exchange moieties and/or cation exchange moieties (30-75 wt.%) and a mixture of a protein capture resin and an electrically conductive material (1-15 wt.%) to a temperature of 60-170 degrees C at a pressure of 0-500 psig for 1-240 minutes to form the electrically conductive flexible and porous material. A material such as sugar, salt, wax and/or camphor is included in the mixture during formation of the porous material.    USE - The method is useful for forming an electrically and ionically conductive flexible and porous material such as wafers, which are useful in a variety of devices such as electrodeionization and separative bioreactors, in the production of organic acids, amino acids, alcohols or esters, for regenerating cofactors in enzymes or microbial cells and in enzyme and/or whole cell based biofuel cells for electricity generation during the operation of the biofuel cell.    ADVANTAGE - The method is capable of economically, rapidly and efficiently forming an electrically and ionically conductive flexible and porous material such as wafers with improved characteristics thus increasing the separation and capture efficiency for enzymatic bioreactors.    DETAILED DESCRIPTION - The method of forming an electrically and ionically conductive flexible and porous material, comprises subjecting a mixture of a thermoplastic binder (25-70 wt.%) and anion exchange moieties and/or cation exchange moieties (30-75 wt.%) and a mixture of a protein capture resin and an electrically conductive material (1-15 wt.%) to a temperature of 60-170 degrees C at a pressure of 0-500 psig for 1-240 minutes to form the electrically conductive flexible and porous material. A material such as sugar, salt, wax and/or camphor is included in the mixture during formation of the porous material, which is removed to provide porosity to the material. The removable material is water soluble, vaporized, sublimated and/or melted to remove the material. The anion exchange moieties and/or cation exchange moieties are initially present as resin beads having a size of 10-1200 mu m. The polymer is initially present as resin beads having a size of 1-75% either larger or smaller than the ion exchange resin beads. The mixture is dry or a slurry containing water, alcohol, or a surfactant.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of a device using the wafers for organic acid production.
