Abstract

SE PRESENTA UN SUMINISTRO DE LIBERACION IONTOFORETICA QUE TIENE UN ELECTRODO DONANTE Y UN CONTRAELECTRODO (11, 12) COMPUESTOS TANTO DE METAL COMO DE UN POLIMERO HIDROFOBICO CARGADO CON UN RELLENO CONDUCTOR. EL DEPOSITO DEL AGENTE (15) EN EL DISPOSITIVO DEL ELECTRODO DONANTE (8) CONTIENE ENTRE UN 10 Y UN 60% DE POLIMERO HIDROFOBICO, ENTRE UN 10 Y UN 60% DE POLIMERO HIDROFILICO, Y MAS DEL 50% DEL AGENTE. SIMILARMENTE, EL DEPOSITO DEL ELECTROLITO (16) CONTIENE ENTRE EL 10 Y 60% DE POLIMERO HIDROFOBICO, ENTRE EL 10 Y 60% DE POLIMERO HIDROFILICO, Y MAS DEL 50% DE ELECTROLITO. EL DEPOSITO DEL AGENTE (15), EL DEPOSITO DEL ELECTROLITO (16) Y LOS ELECTRODOS (11, 12) SE ENCUENTRAN PREFERIBLEMENTE EN FORMA DE PELICULAS QUE ESTAN LAMINADAS UNAS CON OTRAS. EL COMPONENTE DE POLIMERO HIDROFOBICO EN EL DEPOSITO DEL AGENTE / ELECTROLITO (15, 16) EVITA LA DESLAMINACION DEL DEPOSITO DEL ELECTRODO BASADO EN POLIMERO DE METAL (11, 12) INCLUSO DESPUES DE LA HIDRATACION DE LOS DEPOSITOS (15, 16).
