Abstract
An electro-chromic device including a solid or quasi-solid electrolyte layer is disclosed. The electrolyte layer may be a composite polymeric electrolyte layer. The polymeric electrolyte layer may be a conductive transparent adhesive or an optically transparent cured electrolyte. The electrolyte layer may also be a porous optically transparent membrane impregnated or embedded with an electrolytic material. Methods for forming solid or quasi-solid electrolyte layers in-situ in electro-chromic devices are also provided.
Claims22
A device comprising:
- a first transparent conductive layer and a second transparent conductive layer;
- at least one electro-chromic layer disposed between the first transparent conductive layer and the second transparent conductive layer;
- and
- a solid electrolyte layer, disposed between the first transparent conductive layer and the at least one electro-chromic layer and in contact with the at least one electro-chromic layer, to provide ions to active sites in the at least one electro-chromic layer, the ions causing the at least one electro-chromic layer to change color,
- wherein the solid electrolyte layer comprises a composite material comprising at least three major components, each major component present in a concentration greater than or equal to 10 wt. %;
- wherein at least one of the at least three major components comprises different polymers;
- and
- wherein the first transparent conductive layer, the at least one electro-chromic layer, the solid electrolyte layer, and the second transparent conductive layer are disposed on a member of the group consisting of a lens blank and a semi-finished lens blank.

A method comprising:
- providing a first substrate having a first conductive layer and a second substrate having a second conductive layer, wherein the first substrate is a member of the group consisting of a lens blank and a semi-finished lens blank;
- disposing at least one electro-chromic layer over the first conductive layer;
- forming a solid electrolyte layer in situ over the at least one electro-chromic layer, the solid electrolyte being a composite material comprising at least three major components, each major component present in a concentration greater than or equal to 10 wt %;
- wherein the in-situ formation includes disposing one or more precursor materials over the at least one electro-chromic layer;
- wherein the solid electrolyte comprises different polymers;
- and
- assembling the first substrate and the second substrate.
