Abstract

Filters comprising a layer of multiwall carbon nanotubes dispersed on a porous substrate, with or without a layer of single wall carbon nanotubes dispersed on top of the layer of multiwall carbon nanotubes, have been fabricated and shown to be useful for removing constituents from fluids.
