(EN) LAMINATE COMPRISING MULTILAYERED FILM BONDED THROUGH HYDROGEN BOND, SELF-SUPPORTING THIN FILM PROVIDED FROM SAID LAMINATE, AND THEIR PRODUCTION PROCESS AND USE
(FR) STRATIFIE COMPRENANT UN FILM MULTICOUCHE LIE PAR LIAISON HYDROGENE, FILM MINCE AUTOPORTANT FOURNI A PARTIR DUDIT STRATIFIE ET LEUR PROCEDE DE FABRICATION ET UTILISATION
Abstract
(EN) This invention relates to: a laminate comprising a support, a multilayer film assembled via a hydrogen bond thereon, and a thin film thereon; a self-supported thin film obtained from such laminate; a method for producing such laminate comprising allowing a support to come into contact alternately with two or more types of solutions comprising substances to be laminated to form a multilayer film and forming a thin film via a method selected from among vapor deposition, spin coating, and layer-by-layer adsorption; a method for producing a self-supported thin film comprising immersing the laminate in a pH-adjusted aqueous solution to dissolve the multilayer film and to separate the thin film from the support; a thin film for cell culture and a capsule for a controlled-release drug obtained from the laminate; and a sensor, a separation film, a device for catalytic reactions, and a sample slice for transmission assay obtained from such thin film.
(FR) La présente invention concerne un stratifié comprenant un support, un film multicouche lié au support par liaison hydrogène et un film mince également pourvu sur le film multicouche, ainsi qu'un film mince autoportant préparé à partir du stratifié. Elle concerne également un procédé pour fabriquer le stratifié, caractérisé du fait qu'il inclut: la mise en contact du support avec deux solutions ou plus contenant un matériau à empiler en alternance pour former un film multicouche; et la formation d'un film mince par un procédé choisi parmi le dépôt en phase vapeur, le revêtement par centrifugation et l'adsorption alternée. Elle concerne également un procédé pour la fabrication d'un film mince autoportant, caractérisé du fait qu'il inclut l'immersion dudit stratifié dans une solution aqueuse au pH ajusté pour éluer le film multicouche et la séparation du film mince du support. L'invention concerne également un film mince pour culture cellulaire et une capsule destinée à contenir un médicament à libération prolongée, préparée à partir dudit stratifié, ainsi qu'un capteur, une membrane de séparation, un dispositif pour réaction catalytique, et une section mince formant échantillon pour la mesure de la transmission préparés à partir dudit film mince.
