Abstract

UN MATERIAL POROSO (POR EJEMPLO UN PAPEL 6) TIENE POROS CON UNA ESCALA DE TAMAÑOS. UN AGENTE MODIFICANTE DEL PORO (COMPRENDIENDO PARTICULAS 8 DE UNA ESCALA DE TAMAÑOS ESTRECHA) SE INCORPORA SELECTIVAMENTE EN EL INTERIOR DE LOS POROS MAYORES (7) PARA SUMINISTRAR ZONAS (9) DE UN AREA DE SUPERFICIE ALTA. ELLO REDUCE LA PENETRABILIDAD DEL MATERIAL (POR EJ. POR MICROORGANISMOS) MIENTRAS TIENE EFECTOS RELATIVAMENTE PEQUEÑOS SOBRE SU PERMEABILIDAD AL AIRE. EL AGENTE MODIFICADOR (8) PUEDE INCORPORARSE CREANDO UNA DIFERENCIA DE PRESION A LO LARGO DEL MATERIAL (2), Y TRATANDOLO CON UNA DISPERSION (POR EJ. UNA AEROSOL) DE AGENTE MODIFICADOR (8) BAJO CONDICIONES DE BAJA INERCIA E INCORPORANDO SOLAMENTE UNA PEQUEÑA CANTIDAD DEL AGENTE (8) (POR EJ, POR DEBAJO DEL 1%).
