Abstract

SE DESCRIBE UN SENSOR IONICO JUNTO CON EL PROCEDIMIENTO PERTINENTE PARA PREPARARLO, QUE CONTIENE UNA MATRIZ ORGANICA POLIMERA, UN IONOFERO, UN DISPOSITIVO BASADO EN SEMICONDUCTORES DEL TIPO EMOS O ISFET (CHEMFET), QUE CONTIENE EN SU SUPERFICIE OXIDO DE SILICIO ADHERENTE A DICHA MATRIZ ORGANICA POLIMERA, POR MEDIO DE UNA MATRIZ POLISILOXANICA, CARACTERIZADO PORQUE LA MATRIZ POLISILOXANICA SE ELIGE ENTRE LOS ORGANOSILANOS DE FORMULA GENERAL: (FIG. A), DONDE RII, RIII Y RIV, QUE PUEDES SER IGUALES O DIFERENTES, SON GRUPOS ALQUILO O ALCOXI, QUE CONTIENEN DE 1-10 ATOMOS DE CARBONO; RI ES IGUAL A (CH2)PX(CH2)P, DONDE X ES CH2 O UN GRUPO AROMATICO MONO- O POLICONDENSADO O NH O O; P Y G, QUE PUEDEN SER IGUALES O DIFERENTES, SON ENTEROS QUE PUEDEN TENER VALORES COMPRENDIDOS ENTRE 0 Y 10, EXCLUYENDOSE EL VALOR 0 CUANDO X ES NH O O; Y ES -NH2, -OH O -SH; Y QUE LA MATRIZ ORGANICA POLIMERA SE BASA EN UN POLIMERO OBTENIDO POR REACCION DE UNA OLEFINA POLIMERZADA.
