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. An electrochromic device having a layer of transparent polymeric material connected to an electrochromic apparatus, wherein the transparent polymeric material comprises
a coating opposite the electrochromic apparatus and that is capable of reflecting infrared and ultraviolet wavelength radiation;
a coating opposite the electrochromic apparatus and blocks wavelengths of visible radiation capable of initiating chemical decomposition of an electrochromic compound; or
a dielectric coating capable of transmitting light within the range of about 400 nm to 700 nm.

2. An electrochromic device according to claim 1 , wherein the transparent polymeric material is a thermoplastic polymer.

3. An 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.

4. An electrochromic device according to claim 3 , wherein the non-aqueous electrolyte is an ionic liquid.

5. An electrochromic device according to claim 4 , 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.

6. An electrochromic device according to claim 4 , wherein the ionic liquid comprises a cation selected from the group consisting of imidazolium groups, pyridinium groups, pyrrolidinium groups, phosphonium groups, ammonium groups, 1,2,3-triazolium groups, benzothiazolium groups, trichloroaluminate, and sulfonium groups.

7. An electrochromic device according to claim 4 , wherein the ionic liquid is an amphoteric compound.
