Beschreibung
Zusammenfassung:	Disclosed herein is a porous membrane comprising a porous substrate; a porous ceramic coating disposed on the porous substrate; where an average pore size of pores in the porous substrate are larger than an average pore size of pores in the porous coating. Disclosed herein is a method of manufacturing a porous membrane comprising disposing upon a porous substrate a porous ceramic coating, where the porous ceramic coating has an average pore size that is less than an average pore size of the porous substrate. L'invention concerne une membrane poreuse comprenant un substrat poreux ; un enrobage céramique poreux disposé sur le substrat poreux ; une taille de pore moyenne des pores dans le substrat poreux étant supérieure à une taille de pore moyenne des pores dans l'enrobage poreux. L'invention concerne un procédé de fabrication d'une membrane poreuse comprenant la disposition sur un substrat poreux d'un enrobage céramique poreux, l'enrobage céramique poreux ayant une taille de pore moyenne qui est inférieure à une taille de pore moyenne du substrat poreux.
