SURFACE CHARGE ENABLED NANOPOROUS SEMI-PERMEABLE MEMBRANE FOR DESALINATION

摘要

A filter includes a membrane having a plurality of nanochannels (14) formed therein. A first surface charge material (18) is deposited on an end portion of the nanochannels. The first surface charge material includes a surface charge to electrostatically influence ions in an electrolytic solution (20) such that the nanochannels reflect ions back into the electrolytic solution while passing a fluid of the electrolytic solution. Methods for making and using the filter are also provided.
