Claims38
An optical switch film between at least two plates and having an electrical bias between the at least two plates, wherein the optical switching film comprises:
- a porous film.
An optical device, comprising:
- a) a porous film;
- and
- b) at least two plates having the porous film between the at least two plates such that an optical switch is provided for the optical device.
An optical device, comprising:
- a) a multi-layered composite film formed simultaneously and coated on a carrier substrate, wherein the multi-layered composite film includes at least one electrically conductive layer;
- and
- b) at least two plates having the multi-layered composite film between the at least two plates such that an optical switch is provided for the optical device.
A method for simultaneously applying an electrically conductive layer during manufacturing of porous film surfaces, comprising the steps of:
- a) providing a carrier substrate;
- b) coating a releasable porous film onto the carrier substrate;
- and
- c) coating the electrically conductive layer onto the releasable porous film at the same time as the releasable porous film is coated onto the carrier substrate.
A method for forming a releasable electrically conductive film, comprising the steps of:
- a) providing a carrier substrate;
- b) coating a releasable film onto the carrier substrate;
- and
- c) coating the electrically conductive layer onto the releasable film at the same time as the releasable film is coated onto the carrier substrate.
