Disclosed are nanocomposite membranes and methods for making and using same. In one aspect, the nanocomposite membrane comprises a film comprising a polymer matrix and nanoparticles disposed within the polymer matrix, wherein the film is substantially permeable to water and substantially impermeable to impurities. In a further aspect, the membrane can further comprise a hydrophilic layer. In a further aspect, the nanocomposite membrane comprises a film having a face, the film comprising a polymer matrix, a hydrophilic layer proximate to the face, and nanoparticles disposed within the hydrophilic layer, wherein the film is substantially permeable to water and substantially impermeable to impurities. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

L'invention porte sur des membranes nanocomposites et sur des procédés de fabrication et d'utilisation associés. Dans un aspect, la membrane nanocomposite comprend un film contenant une matrice polymère et des nanoparticules disposées dans la matrice polymère, ce film étant sensiblement perméable à l'eau et sensiblement imperméables aux impuretés. Dans un autre aspect, la membrane contient aussi une couche hydrophile. Selon un aspect différent, la membrane nanocomposite comprend un film doté d'une face, ce film comprenant une matrice polymère, une couche hydrophile à proximité de la face, et des nanoparticules disposées dans la couche hydrophile, ce film étant sensiblement perméable à l'eau et sensiblement imperméable aux impuretés.
