Disclosed is a process of preparing a porous composite membrane by depositing a dispersion of discrete particles on a porous substrate to obtain a composition, and stabilizing the composite. Also disclosed is a porous composite membrane comprising a stable array of partially coalesced particles on the surface of a porous substrate.
L'invention se rapporte à un procédé pour préparer une membrane composite poreuse, en déposant une dispersion de particules séparées sur un substrat poreux, afin d'obtenir un composite, puis en stabilisant ce composite. L'invention concerne également une membrane composite poreuse comportant une matrice stable de particules partiellement coalescées sur la surface d'un substrat poreux.
