Abstract
A membrane includes a polymeric material; and a nanomaterial dispersed in the polymeric material, wherein the nanomaterial includes a carbon nanotube material, and the membrane is hydrophilic. A method for forming a membrane includes distributing a nanomaterial in a solvent to form a first mixture, wherein the nanomaterial includes a multi-walled carbon nanotube material; mixing one or more polymeric materials with the first mixture to form a second mixture; introducing a non-solvent sufficient to induce phase separation; and drying to form a hydrophilic membrane.
Claims21
A membrane, the membrane comprising:
- a polymeric material;
