A method for producing a separation membrane, comprising the steps of passing a solution of a precursor of the separation membrane through a through-pore formed in a porous monolithic material to form a film made of the solution on the surface of the through-pore, and then drying the film to form the separation membrane, wherein the drying process is conducted by air drying in which hot air is passed through the through-pore.

La présente invention concerne un procédé de production d'une membrane de séparation, comprenant les étapes consistant à faire passer une solution d'un précurseur de la membrane de séparation à travers un pore traversant formé dans un matériau monolithique poreux pour former un film réalisé à partir de la solution sur la surface du pore traversant, puis à sécher le film pour former la membrane de séparation, le processus de séchage étant réalisé par un séchage à l'air au cours duquel l'air chaud est amené à passer à travers le pore traversant.
