Claim 1

1 . A method of making a device for active modification of thermal radiation, the method comprising: (a) providing a non-metallic substrate; (b) depositing a liquid composition comprising carbon nanotubes onto the substrate to form a first electrode; (c) depositing a liquid comprising a polymer and an ionic liquid onto the first electrode to form a polymeric permeable membrane comprising the ionic liquid; and (d) depositing a liquid composition comprising carbon nanotubes onto the polymeric permeable membrane to form a second electrode. (a) providing a non-metallic substrate; (b) depositing a liquid composition comprising carbon nanotubes onto the substrate to form a first electrode; (c) depositing a liquid comprising a polymer and an ionic liquid onto the first electrode to form a polymeric permeable membrane comprising the ionic liquid; and (d) depositing a liquid composition comprising carbon nanotubes onto the polymeric permeable membrane to form a second electrode.
