Abstract

SE PRESENTA UN METODO PARA HACER UN MATERIAL POLIMERICO POROSO CALENTANDO UNA MEZCLA QUE COMPRENDE UN FLUORURO DE POLIVINILIDENO Y UN SISTEMA SOLVENTE QUE INICIALMENTE COMPRENDE UN PRIMER COMPONENTE QUE ES UN SOLVENTE LATENTE DE FLUORURO DE POLIVINILIDENO Y UN SEGUNDO COMPONENTE QUE NO ES SOLVENTE PARA EL FLUORURO DE POLIVINILIDENO EN DONDE, A TEMPERATURA ELEVADA, EL FLUORURO DE POLIVINILIDENO SE DISUELVE EN EL SISTEMA SOLVENTE PARA PRODUCIR UNA SOLUCION OPTICAMENTE CLARA, LA SOLUCION SE ENFRIA RAPIDAMENTE DE MANERA QUE TENGA LUGAR LA SEPARACION DE FASE LIQUIDO-LIQUIDO DE NO EQUILIBRIO PARA FORMAR UNA FASE CONTINUA RICA EN POLIMERO Y UNA FASE CONTINUA POBRE EN POLIMERO SIENDO ENTREMEZCLADAS LAS DOS FASES EN FORMA DE UNA MATRIZ BICONTINUA DE UN AREA INTERFACIAL GRANDE, Y EL ENFRIAMIENTO SE CONTINUA HASTA QUE LA FASE RICA EN POLIMERO SE SOLIDIFIQUE. LA FASE PROBRE EN POLIMERO SE ELIMINA DEL MATERIAL POLIMERICO SOLIDO. EL MATERIAL POROSO ASI SEPARADO SE CARACTERIZA POR UNA ESTRUCTURA FILAMENTOSA QUE CONSTA DE UNA PLURALIDAD DE HEBRAS DE POLIMERO (1) CONECTADAS ENTRE SI EN UN NUMERO DE UBICACIONES (2) SEPARADAS A LO LARGO DE CADA HEBRA.
