METHOD FOR MODIFYING SURFACE OF ALUMINUM OXIDE AND ELECTROOSMOSIS PUMP AND ELECTRIC POWER GENERATOR USING MODIFIED ALUMINUM OXIDE MEMBRANE

摘要

The invention provides a method for modifying a surface of aluminum oxide. Aluminum oxide is contacted with a hydrogen peroxide aqueous solution having 5-70 volume % of hydrogen peroxide for 20 minutes to 3 hours. The invention also provides an electroosmosis pump and electric power generator having a porous aluminum oxide membrane modified by the above method.
