Abstract

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.
