Flexible dimming device and its fabrication method, glass assembly, automobile, and glass curtain wall

A fabrication method of a flexible dimming device, comprising:

• forming a first composite substrate, including:
• providing a first glass substrate, forming a sixth adhesive film on a side of the first glass substrate, coating an anti-ultraviolet film on a side of the sixth adhesive film away from the first glass substrate, forming a first adhesive film on a side of the anti-ultraviolet film away from the first glass substrate, bonding a first flexible substrate on a side of the first adhesive film away from the first glass substrate, and forming a first electrode on the side of the first flexible substrate away from the first glass substrate, wherein the sixth adhesive film includes ultraviolet dissociation adhesive;
• forming a second composite substrate, including:
• providing a second glass substrate, forming a seventh adhesive film on a side of the second glass substrate, bonding a second flexible base on a side of the seventh adhesive film away from the second glass substrate, and forming a second electrode on the side of the second flexible substrate away from the second glass substrate, wherein the seventh adhesive film includes ultraviolet dissociation adhesive;
• coating a side of the first electrode in the first composite substrate with a sealant material wherein the sealant material surrounds and defines a first region of guest-host liquid crystals and dye molecules, dripping the guest-host liquid crystal and the dye molecules into the first region, and bonding the second composite substrate such that the second electrode is located on a side of the second flexible substrate close to the first composite substrate;
• or, coating a side of the first electrode in the first composite substrate with a sealant material wherein the sealant material surrounds and defines a first region of guest-host liquid crystals and dye molecules and a channel for guest-host liquid crystals and dye molecules is preserved, bonding the first composite substrate and the second composite substrate, and injecting the guest-host liquid crystals and dye molecules through the channel;
• irradiating the sealant material with ultraviolet rays on the side of the second glass substrate away from the first glass substrate to cure the sealant material to form a sealant;
• irradiating the first composite substrate with ultraviolet rays on the side of the first composite substrate away from the second composite substrate, to dissociate the sixth adhesive film and peel off the first glass substrate, and then irradiating the second composite substrate with ultraviolet rays on the side of the second composite substrate away from the first composite substrate to dissociate the seventh adhesive film and peel off the second glass substrate to obtain the flexible dimming device;
• or, irradiating the second composite substrate with ultraviolet rays on the side of the second composite substrate away from the first composite substrate, to dissociate the seventh adhesive film and peel off the second glass substrate, and then irradiating the first composite substrate with ultraviolet rays on the side of the first composite substrate away from the second composite substrate to dissociate the sixth adhesive film and peel off the first glass substrate to obtain the flexible dimming device.
