Abstract

UN METODO PARA FABRICAR UN MATERIAL POLIMERICO POROSO CALENTANDO UNA MEZCLA QUE COMPRENDE FLUORURO DE POLIVINILDENO Y UN SISTEMA DISOLVENTE QUE COMPRENDE, INICIALMENTE, UN PRIMER COMPONENTE QUE ES UN DISOLVENTE LATENTE PARA EL FLUORURO DE POLIVINILDENO Y UN SEGUNDO COMPONENTE QUE NO ES UN DISOLVENTE PARA EL FLUORURO DE POLIVINILDENO EN DONDE, A TEMPERATURA ELEVADA, EL FLUORURO DE POLIVINILDENO SE DISUELVE EN EL SISTEMA DISOLVENTE PARA PROPORCIONAR UNA SOLUCION OPTICAMENTE TRANSPARENTE. A CONTINUACION, LA SOLUCION SE ENFRIA RAPIDAMENTE PARA QUE NO TENGA LUGAR UNA SEPARACION DE FASE LIQUIDO-LIQUIDO NO EQUILIBRADA CON EL FIN DE FORMAR UNA FASE CONTINUA RICA EN POLIMERO Y UNA FASE CONTINUA POBRE EN POLIMERO ENTREMEZCLANDOSE LAS DOS FASES EN FORMA DE UNA MATRIZ BICONTINUA CON UNA GRAN AREA INTERFACIAL, Y SE PROSIGUE CON EL ENFRIADO HASTA QUE LA FASE RICA EN POLIMERO SE SOLIDIFICA. SE EXTRAE LA FASE POBRE DE POLIMERO DEL MATERIAL POLIMERICO SOLIDO. UN MATERIAL POROSO PREPARADO DE ESTA FORMA SE CARACTERIZA POR UNA ESTRUCTURA FINA O FILAMENTOSA FORMADA POR UNA PLURALIDAD DE HEBRAS DE POLIMERO (1) UNIDAS EN MUCHOS LUGARES (2) ESPACIADOS A LO LARGO DE CADA HEBRA.
