The invention relates to a procedure for functionalization of a substrate starting from a molecular compound, wherein said substrate is a porous membrane, organic or inorganic and insoluble in aqueous medium, and said compound is a functional compound, insoluble in aqueous medium and soluble in an organic solvent miscible in water, and said procedure comprises preparing an aqueous suspension of nanoparticles of said functional molecular compound, where the size of the nanoparticles is equal or less than the pore size of said membrane, and filtering said suspension through said substrate, in such a way that said nanoparticles coalesce together and with the substrate so that both become closely joined. The invention also relates to the substrate thus obtained, use thereof and the device containing same.
L'invention se rapporte à un procédé de fonctionnalisation d'un substrat à partir d'un composé moléculaire, lequel substrat est une membrane poreuse, organique ou inorganique, insoluble en milieu aqueux, et lequel composé moléculaire est un composé fonctionnel, insolubles en milieu aqueux et soluble dans un dissolvant organique hydromiscible. Ce procédé consiste à préparer une suspension aqueuse de nanoparticules du composé moléculaire fonctionnel, la taille des nanoparticules étant égale ou inférieure à la taille des pores de la membrane, et à filtrer cette suspension à travers ce substrat de manière que les particules soient en coalescence mutuelle et avec le substrat, le tout étant intimement uni. L'invention se rapporte aussi au procédé ainsi obtenu, à son utilisation et au dispositif le comprenant.
