Title (EN) SUPPORTED ZEOLITE FILMS AND METHODS FOR PREPARING
(FR) FILMS DE ZÉOLITE SUR SUPPORT ET PROCÉDÉS DE PRÉPARATION
Abstract:
(EN) The invention concerns a method for producing a crystalline film comprising zeolite and/or zeolite-like crystals on a porous substrate. The method comprises the steps of: providing a porous support; modifying at least a surface of the top-layer of said porous support by treatment with a composition comprising one or more cationic polymer(s); rendering at least the outer surface of said porous support hydrophobic by treatment with a composition comprising one or more hydrophobic agent(s); subjecting said treated porous support to a composition comprising zeolite and/or zeolite-like crystals thereby depositing and attaching zeolite and/or zeolite- like crystals on said treated porous support, and growing a crystalline film comprising zeolite and/or zeolite-like crystals on said treated porous support and calcination. Crystalline films find use in a variety of fields such as in the production of membranes, catalysts etc.
(FR) L'invention concerne un procédé de production d'un film cristallin comprenant des cristaux de zéolite ou de type zéolite sur un substrat poreux. Le procédé comprend les étapes consistant à : fournir un support poreux; modifier au moins une des surfaces de la couche supérieure dudit support poreux par traitement avec une composition comprenant un ou plusieurs polymères cationiques; à rendre hydrophobe au moins la surface externe dudit support poreux par traitement avec une composition comprenant un ou plusieurs agents hydrophobes; à soumettre ledit support poreux traité à une composition comprenant des cristaux de zéolite et/ou de type zéolite, ce qui permet de déposer et de fixer des cristaux de zéolite et/ou de type zéolite sur ledit support poreux traité, et de faire croître un film cristallin comprenant des cristaux de zéolite et/ou de type zéolite sur ledit support poreux traité et la calcination. Les films cristallins trouvent une utilisation dans une variété de domaines tels que dans la production de membranes, de catalyseurs, etc.
