Abstract

Disclosed are curved electrochromic devices comprising an electrochromic apparatus disposed between first and second curved layers of transparent material, and the first and second curved layers have exterior and inner surfaces, wherein the inner surfaces face the electrochromic apparatus. Also disclosed are processes for manufacturing the disclosed bubble visors.

First claim

What is claimed is:

1. A curved electrochromic device comprising an electrochromic apparatus disposed between first and second curved layers of transparent material, and the first and second curved layers have exterior and inner surfaces, wherein the inner surfaces face the electrochromic apparatus, and wherein the exterior surface of the first curved layer of transparent material is provided with a coating that blocks wavelengths of visible radiation capable of initiating chemical decomposition of the electrochromic apparatus.

2. A curved electrochromic device according to claim 1 , wherein the transparent material of each of the first and second curved layers is independently glass or thermoplastic polymer.

3. A curved electrochromic device according to claim 2 , wherein the polymer is a thermoplastic polymer, a silicone, a silicone polyether, a silicone acrylic, a polyacrylate, a polyethylene oxide, a fluorine resin, a vinylidene fluoride-based fluorine rubber, or an epoxy resin.

4. A curved electrochromic device according to claim 2 , wherein at least one of the membrane first surface and the membrane second surface is in contact with an electrochromic compound.

5. A curved electrochromic device according to claim 1 , wherein the electrochromic apparatus comprises an electrolyte membrane comprising a non-aqueous electrolyte and a polymer, and the electrolyte membrane has a membrane first surface and a membrane second surface.

6. A curved electrochromic device according to claim 5 , wherein the non-aqueous electrolyte is an ionic liquid.

7. A curved electrochromic device according to claim 6 , wherein the ionic liquid comprises an anion selected from the group consisting of sulfates, alkylsulfates, arylsulfates, alkylsulfonates, fluorinated alkylsulfates, fluorinated alkylsulfonates, fluoroalkylsulfonylimides, hexafluorophosphate, tetracyanoborate, tetrafluoroborate, thiocyanate, thiosalicylate, dicyanamide, and halides.

8.
