Abstract

Il est décrit un procédé de production dun tamis moléculaire perméable à leau dans lequel un substrat poreux ayant des pores de taille de micron a déposé, sur une surface des pores, des plaquettes bidimensionnelles et non poreuses pour étanchéifier, à la surface du substrat, des pores dans un substrat poreux afin de former une couche de plaquettes bidimensionnelles. Un produit détanchéité durcissable est déposé sur la couche de plaquettes bidimensionnelles et toute zone exposée restante de la surface du substrat poreux, et durcissant le produit détanchéité durcissable afin de former une couche étanche sur la surface du substrat poreux afin dempêcher un contournement, par leau, des plaquettes bidimensionnelles et non poreuses et afin dempêcher un passage à travers le substrat poreux. Un réseau de sub-nanopores est ensuite produit à travers la couche étanche, le réseau de sub-nanopores ayant une taille permettant à leau de passer à travers de la couche étanche mais non pas aux ions de métal de donner un tamis moléculaire perméable à leau caractérisé par une perméabilité deau à de faibles pressions différentielles.
