WIPO Patent Application WO/2023/197231

A1

Provided are a light valve and a switchable glass. The light valve comprises a first transparent electrode disposed on a first transparent substrate, a second transparent electrode arranged on a second transparent substrate, and a light control layer arranged between the first transparent electrode and the second transparent electrode, wherein a first protective layer is arranged between the first transparent electrode and the light control layer, and a second protective layer is arranged between the second transparent electrode and the light control layer; and the first protective layer and/or the second protective layer comprises a solid modified siloxane polymer, and comprises the following components in percentages by mass: 45-100 parts of the solid modified siloxane polymer, 0-3 parts of an antioxidant, 0-3 parts of an ultraviolet absorbent, 0-3 parts of an infrared absorbent, 0-3 parts of a light stabilizer, 0-3 parts of a heat stabilizer, and 0-40 parts of a liquid additive. The solution of the present invention can greatly improve the overall thermal stability and light stability of the light valve, and also obtain a higher interlayer adhesive force.
