Title (EN) MANUFACTURING METHOD FOR BIOABSORBABLE MEMBRANE AND BIOABSORBABLE MEMBRANE
(FR) PROCÉDÉ DE FABRICATION DE MEMBRANE BIOABSORBABLE ET MEMBRANE BIOABSORBABLE ASSOCIÉE
(JA) 生体吸収性膜の製造方法及び生体吸収性膜
Abstract:
(EN) One aspect of the present invention comprises, in a manufacturing method for a bioabsorbable membrane, a step for forming a liquid membrane by spin-coating a coating solution comprising a first bioabsorbable polymer and a solvent; and a step for forming a dense layer by bringing a porous membrane comprising a second bioabsorbable polymer into contact with the liquid membrane.
(FR) Un aspect de la présente invention concerne un procédé de fabrication d'une membrane bioabsorbable comprenant : une étape de formation d'une membrane liquide par dépôt à la tournette d'une solution de revêtement comprenant un premier polymère bioabsorbable et un solvant ; et une étape de formation d'une couche dense par mise en contact d'une membrane poreuse comprenant un deuxième polymère bioabsorbable avec la membrane liquide.
(JA) 本発明の一態様は、生体吸収性膜の製造方法において、第一の生体吸収性ポリマー及び溶媒を含む塗布液をスピンコートして、液膜を形成する工程と、該液膜に、第二の生体吸収性ポリマーを含む多孔質膜を接触させて、緻密層を形成する工程を含む。
