MULTILAYER FILM WITH ELECTRICALLY SWITCHABLE OPTICAL PROPERTIES AND IMPROVED ELECTRICAL CONTACT Russian patent published in 2022 - IPC B32B17/10 

FIELD: layered materials.

SUBSTANCE: group of inventions relates to a multilayer film with electrically switchable optical properties, insulated glazing, a method for manufacturing the multilayer film with electrically switchable optical properties, and an application of the multilayer film. The multilayer film with electrically switchable optical properties includes at least a first substrate film, a first conductive layer, an active layer, a second conductive layer, and a second substrate film, arranged over the surface in the indicated order. The multilayer film in surface thereof has at least one first cutout, and at least one first cutout in the form of a through hole passes through all layers of the multilayer film. The first cutout is filled with a conductive filler in conductive contact with the first conductive layer in the first cutout, and the first busbar is in conductive contact with the conductive filler.

EFFECT: group of inventions is aimed at providing a multilayer film with electrically switchable optical properties, characterised by improved electrical contact, insulated glazing including such a multilayer film, and a cost-efficient method for manufacture thereof.
