Embodiment 1

[0089] In Example 1, a roll-to-roll sputtering apparatus having two film-forming chambers, a first film-forming chamber equipped with a first film-forming roller and a second film-forming chamber equipped with a second film-forming roller, was used on a transparent film substrate. A Mg-Y dimming layer and a Pd catalyst layer are formed on it. The Mg—Y target was arranged to face the first film-forming roll of the sputtering apparatus, and the Pd target was arranged to face the second film-forming roll. As the Mg-Y target, a Mg-Y divided target (manufactured by RARE METALLIC Co., Ltd.) having a Mg metal plate and a Y metal plate at an area ratio of an erosion part of 2:5 was used. As the Pd target, a Pd metal target (manufactured by Tanaka Kikinzoku Co., Ltd.) was used.

Embodiment 2、3

[0093] In Example 2 and Example 3, the same roll-to-roll sputtering device as in Example 1 was used, and the Pd target was arranged to face the first film-forming roll, and the Mg-Y target was placed to face the second film-forming roll. , forming a Mg-Y dimming layer and a Pd catalyst layer on a transparent film substrate. A roll of PET film with a thickness of 188 μm is installed on the unwinding roller of the sputtering device, the PET film is sent out from the unwinding roller and moved at 1 m / min in the device, and the discharge from the cathode facing the first film forming roller Closed, on the second film-forming roll, the light-adjusting layer formed of Mg-Y alloy is formed into a film by DC sputtering, and the film is wound up with a take-up roll. Thereafter, under the state of maintaining the vacuum environment, the discharge from the cathode facing the second film-forming roll is turned off, and the discharge from the cathode facing the first film-forming roll is t...

Abstract

A hydrogen activation type light-modulating film (1) which comprises a polymeric film base (10) and, disposed thereon, a light-modulating layer (30) and a catalyst layer (40), and which is switched between a transparent state and a reflective state by means of hydrogenation and dehydrogenation. A light-modulating layer which reversibly changes in state between a transparent state due to hydrogenation and a reflective state due to dehydrogenation and a catalyst layer which accelerates the hydrogenation and dehydrogenation in the light-modulating layer are formed on a polymeric film base by roll-to-roll sputtering. The film deposition from formation of the light-modulating layer to formation of the catalyst layer is continuously performed while keeping the system unopen to the air.

Description

technical field [0001] The invention relates to a method for manufacturing a dimming film with a hydrogen active dimming layer and a catalyst layer on a transparent film substrate. Background technique [0002] Dimming elements are used in windowpanes, interior materials, and the like of buildings and vehicles. In particular, in recent years, from the viewpoint of reducing the load of air-conditioning and heating equipment, reducing the load of lighting, and improving comfort, the demand and expectation for light-adjusting elements have increased. Among them, the hydrogen-activated light-adjusting element that switches the transmission and reflection of light by hydrogenation and dehydrogenation of the light-adjusting material has the following advantages. Obtain high energy saving effect. In addition, since hydrogenation and dehydrogenation can be switched by an aerochromic method, it is easy to enlarge the area. [0003] As hydrogen-active light-adjusting materials capa...
