Claims31
A method of aligning nanopores in a polymeric film, comprising the steps of:
- depositing a solution of at least one monomer in a solvent onto a surface of a first substrate to form a mesophase comprised of nanopores;
- applying a second substrate onto a surface of the mesophase, such that the mesophase is in contact with both the first substrate and the second substrate, and wherein the nanopores at least partially align in response to the second substrate;
- and
- polymerizing the mesophase to form a polymeric film containing the at least partially aligned nanopores.

A composite material, comprising:
- a first substrate;
- a second substrate;
- and
- a layer between the first and second substrate, the layer comprising at least one monomer, at least one photoinitiator and a plurality of nanopores;
- wherein the plurality of nanopores are at least partially aligned in the layer.

A method of fabricating a polymeric film of aligned nanopores, comprising the steps of:
- depositing a mixture of at least one monomer and at least one template compound onto a surface of a first substrate to form a mesophase;
- polymerizing the mesophase to form a polymeric film;
- rinsing the polymeric film with NaOH in DMSO to remove the template compound;
- and
- wetting the polymeric film with water to form aligned nanopores.
