Abstract: This application relates to an imprinting apparatus and method. In one aspect, the imprinting apparatus applies pressure between a master substrate and a polymer film to transfer a pattern formed on the master substrate to the polymer film. The imprinting apparatus includes a plurality of coils and the surface of the master substrate is heated by an electromagnetic field induced by the plurality of coils. Through holes are defined in each of the plurality of coils, and support bars are inserted into the through holes. The positions of the plurality of coils are changed corresponding to the master substrate.

Abstract: The present application relates to a heat generating side window, for a vehicle, comprising: a substrate comprising an upper edge, a lower edge, a front edge and a rear edge; a heat generating member positioned adjacently to the substrate; an upper busbar positioned on the heat generating member and electrically connected to the heat generating member; and a lower busbar positioned on the heat generating member and electrically connected to the heat generating member.

Abstract: A transparent electrode or a transparent heat trace is manufactured by transferring a silver nanowire formed on a glass substrate to a polymer and a flexible film. When the silver nanowire transferred to the polymer and the flexible film is processed with an iodine mixture, a surface of the silver nanowire is discolored.

Abstract: A transparent heating film according to an embodiment includes: a transparent substrate including a top surface in which a plurality of grooves are formed and a flat bottom surface; and a plurality of metal nanostructures located on the top surface of the transparent substrate. The metal nanostructures have a first distance from a middle plane of the transparent heating film, and an imaginary line extending from the top surface of the transparent substrate has a second distance from the middle plane of the transparent heating film. The transparent heating film includes a first region in which the first distance is shorter than the second distance, and the first distance is a shortest distance between a first point at which each of the metal nanostructure and the transparent substrate are in contact with each other and the middle plane, the first point being located in each of the grooves.

Abstract: This application relates to an apparatus and method for manufacturing a transparent electrode. One surface of a base substrate is surface-treated with a predetermined material or predetermined light. A conductive material and a hydrophilic solution are sprayed onto the surface-processed base substrate by using a spray block including a spray nozzle and a thermographic camera. The conductive solution is sprayed onto the processed base substrate to form a surface heating body. The surface heating body is heated to be photographed by the thermographic camera. A controller analyzes a photographed image to define an area of supplementation and form a supplemented surface heating body in the area of supplementation by using the spray nozzle, and thus a transparent electrode having uniform heating characteristics is manufactured.
