FUNCTIONALITY OF CELLULOSE BY IMPREGNATION OF INORGANIC SUBSTANCES

Functionalities of cellulose with inorganic substances were examined i n the forms of membrane and fiber. Cellulose membranes impregnated wit h iron oxide, metal (Pd, Ru, Rh) particles, and silver particles acted as Donnan effective permselective membrane, hydrogenation-catalytic m embrane, and surface-enhanced Raman scattering active substrate, respe ctively. Enzyme was entrap-immobilized onto cellulose-TiO2 (ZrO2) gel fiber via gel formation of cellulose with metal alkoxide. The entrap-i mmobilized fiber is stable in common solvents, phosphate and electroly te solution over a wide range of pH values (4-10).
