Abstract

LA INVENCION SE REFIERE A MEMBRANAS CON UN DOBLE REVESTIMIENTO UTILES COMO MEMBRANAS DE UNA DIRECCION O DE RECTIFICACION QUE REDUCEN EL QUE LAS MOLECULAS DE SOLUTOS SE VUELVAN A FILTRAR EN UNA DIALISIS Y QUE MEJORAR EL SUMINISTRO DE SUSTANCIAS NUTRITIVAS Y LA RECUPERACION DEL PRODUCTO EN LOS BIORREACTORES DE MEMBRANA. LAS MEMBRANAS SON MATERIALES POLIMERICOS CON UN DOBLE REVESTIMIENTO A MODO, PREFERENTEMENTE, DE FIBRAS HUECAS. LAS MEMBRANAS TIENEN REVESTIMIENTOS DE POLIMEROS EN LAS CARAS OPUESTAS CON UNAS CARACTERISTICAS DE POROSIDAD O DE LOS COEFICIENTES DE CRIBADO DIFERENTES. LAS MEMBRANAS SE FORMAN A BASE DE EXTRUIR UN POLIMERO DISUELTO EN UN SOLVENTE AL TIEMPO QUE POR LO MENOS UNA SUPERFICIE SE PONEN EN CONTACTO CON UN NO SOLVENTE MISCIBLE CON EL SOLVENTE. LA OTRA SUPERFICIE SE PONE EN CONTACTO CON UN NO SOLVENTE. LOS DOS NO SOLVENTES SON BIEN DIFERENTES ENTRE SI O BIEN UNO DE LOS NO SOLVENTES CONTIENE UN ADITIVO SOLUBLE QUE CAMBIA LA POROSIDAD DEL REVESTIMIENTO FORMADO EN EL POLIMERO EXTRUIDO DISUELTO. SE PUEDEN FORMAR DISPOSITIVO DE DIALISIS MEJORADOS SI SE UTILIZAN, COMO ELEMENTO DE DIALISIS, MANOJOS DE LAS MEMBRANAS DE FIBRAS HUECAS QUE TENGAN PROPIEDADES RECTIFICADORAS. SE PUEDEN FORMAR BIORREACTORES MEJORADOS SI SE UTILIZAN MANOJOS DE MEMBRANAS DE FIBRAS HUECAS COMO RECIPIENTE DE CULTIVO QUE TENGA PROPIEDADES RECTIFICADORAS.
