An electro-optic device may comprise a first substrate having a first surface and a second surface; a second substrate having a third surface and a fourth surface, the second substrate disposed in a spaced-apart relationship relative to the first substrate such that the second and third surfaces are generally parallel to and face one another; a first electrode associated with the second surface; a second electrode associated with the third surface; a styrene-ethylene-butylene-styrene (SEBS) anionic exchange membrane disposed between the first and second electrodes; a first compartment defined by the SEBS anionic exchange membrane and the first substrate; a second compartment defined by the SEBS anionic exchange membrane and the second substrate; a cathodic species disposed in the first compartment; and an anodic species disposed in the second compartment.

Electro-optic devices made with SEBS membranes

A medium for an electro-optic element includes a first block copolymer unit including at least one of a first di-block copolymer and first tri-block copolymer and at least one of a donor compound or an acceptor compound conjugated with the at least one of the first di-block copolymer and first tri-block copolymer, thereby forming the first block copolymer unit. The medium further includes a second block copolymer unit including at least one of a second di-block copolymer and second tri-block copolymer conjugated with the at least one of the donor compound and the acceptor compound, thereby linking the first block copolymer unit with the second block copolymer unit.

A medium for an electro-optic element includes a first block copolymer unit including at least one of a first di-block copolymer and first tri-block copolymer and at least one of a first donor compound and first acceptor compound conjugated with the at least one of the first di-block copolymer and first tri-block copolymer, thereby forming the first block copolymer unit. The medium further includes a second block copolymer unit including at least one of a second di-block copolymer and second tri-block copolymer and at least one of a second donor compound and a second acceptor compound conjugated with the at least one of the second di-block copolymer and second tri-block copolymer, thereby forming the second block copolymer unit. The first block copolymer unit is polymerized with the second block copolymer unit.
