Outline of Final Research Achievements

Carbon nanotubes with excellent electroconductivity were distributed in biopolymer collagen to fabricate CNT/collagen composites and porous structures of the composites with enzymes were developed for electrodes of bio-fuel cell. Because of the structural unstability of the erectrodes, chemical cross-linking was introduced into the collagen phases. Furthermore, cellulose film coating was used to develop new electrode materials without drain of enzymes. Finally, the cellulose cated CNT/collagen porous materials with enzymes were successfully used as electrodes of a bio-fuel cell and stable electric generation was obtained by the cell.
