(ZH) 包含由氢键结合的多层膜的层叠体、由该层叠体获得的自支持薄膜、及它们的制法和用途
Abstract
(EN) This invention provides a laminate comprising a support, a multilayered film bonded onto the support through a hydrogen bond, and a thin film further provided on the multilayered film, a self-supporting thin film prepared from the laminate, a process for producing the laminate, characterized by comprising bringing a support into contact with two or more solutions containing a material to be stacked alternately to form a multilayered film, and forming a thin film by a method selected from vapor deposition, spin coating, and alternate adsorption, a process for producing a self-supporting thin film, characterized by comprising immersing the above laminate in a pH-adjusted aqueous solution to elute the multilayered film and separating the thin film from the support, a thin film for cell culture and a capsule for a sustained release medicament prepared from the above laminate, and a sensor, a separation membrane, a device for a catalytic reaction, and a sample thin section for transmission measurement prepared from the above thin film.
