Abstract
Methods herein disclosed include methods of producing a nanoporous membrane by coating a planar substrate (204) with a solution (solution tank 201) containing a reactive metal adatom. The coated planar substrate can then be perforated by initiating a redox reaction between the reactive metal adatom and the planar substrate that causes the reactive metal adatom to remove material, forming nanoscale pores in the planar substrate that result in a nanoporous planar material. This nanoporous planar material can be formed into a nanoporous membrane.
Claims9
A method of producing a nanoporous membrane, the method comprising:
- coating a planar substrate with reactive metal adatoms to form a coated planar substrate in which the reactive metal adatoms are in contact with the planar substrate;
- accomplishing an oxidation-reduction (REDOX) reaction between the reactive metal adatoms and the planar substrate in the coated planar substrate that causes the reactive metal adatoms to form nanoscale pores in the planar substrate to form a nanoporous planar material;
- and
- forming the nanoporous planar material into a nanoporous membrane, wherein forming the nanoporous membrane comprises:
- depositing flakes of the nanoporous planar material onto a porous substrate;
- compressing the flakes of the nanoporous planar material and the porous substrate, wherein compressing the flakes of the nanoporous planar material and the porous substrate comprises feeding the flakes of the nanoporous planar material and the porous substrate through compression rollers;
- and
- cleaving the nanoporous membrane from the porous substrate.
