Abstract

SE DESCRIBE UN MATERIAL MICROPOROSO EN EL QUE ESTAN INCLUIDAS FIBRAS DE CARBONO QUE PRESENTAN UNA DISTRIBUCION TAL DE SUS LONGITUDES QUE LA LONGITUD MEDIA DE AL MENOS EL 80% DE LAS FIBRAS CORRESPONDE A LA LONGITUD MEDIA DE ESTAS, INCREMENTADA O DISMINUIDA EN APROXIMADAMENTE UN 20%. ESTE MATERIAL SE PREPARA MEDIANTE UN PROCEDIMIENTO QUE COMPRENDE DEPOSITAR SOBRE UN SUSTRATO RIGIDO POROSO UNA SUSPENSION QUE CONTIENE UN AGLUTINANTE Y LAS FIBRAS DE CARBONO, CUIDANDO DE QUE SE MANTENGA LA DISTRIBUCION DE LONGITUDES ANTES INDICADA. EL MATERIAL OBTENIDO ES ESPECIALMENTE UTIL PARA LA REALIZACION DE ELEMENTOS CATODICOS EMPLEADOS EN LA ELECTROLISIS DEL CLORURO DE SODIO.
