Embodiment 1
[0027] Example 1 Cut a silk fabric with a size of 1 cm x 1 cm, soak it in dilute NaOH solution for 20 min, take it out and rinse it with deionized water several times, dry it at room temperature, and set aside; weigh 1 g of butane tetracarboxylic acid, diphosphate Sodium hydrogen 0.35 g and the treated silk fabric were put into deionized water, stirred for 1 hour, rinsed, pressed, prebaked at 80°C for 5 minutes, and baked at 160°C for 3 minutes to obtain butane tetracarboxylic acid modified silk The fabric was then placed in a 20 mL hydrothermal kettle with deionized water as the medium and added butane tetracarboxylic acid and EuCl 3 ×6H 2 O, its molar ratio is 2:1, EuCl 3 ×6H 2 The mass of O is 0.01 g. After hydrothermal reaction at 100°C for 24 h, it is cooled to room temperature, filtered out, rinsed repeatedly with deionized water, and dried at room temperature to prepare a fluorescent silk fabric whose surface is rare earth Eu and butane tetracarboxylate. Acid-assembl...
Embodiment 2
[0028] Example 2 Cut a silk fabric with a size of 1 cm x 1 cm, soak it in dilute NaOH solution for 30 min, take it out and rinse it with deionized water several times, dry it at room temperature, and set aside; weigh 1.5 g of pyromellitic acid, diphosphate Sodium hydrogen 0.5 g and the treated silk fabric were put into deionized water, stirred for 1 hour, rinsed, pressed, pre-baked at 70°C for 5 minutes, and baked at 150°C for 3 minutes to obtain the silk grafted with pyrenetetracarboxylic acid. The fabric was then placed in a 20 mL hydrothermal kettle with deionized water as the medium and added pyromellitic acid and TbCl 3 ×6H 2 O, its molar ratio is 2:1, TbCl 3 ×6H 2 The quality of O is 0.02 g. After hydrothermal reaction at 120°C for 36 h, it is cooled to room temperature, filtered out, rinsed repeatedly with deionized water, and dried at room temperature to prepare a fluorescent silk fabric whose surface is rare earth Tb and pyromellitic tetracarboxylate. Acid-assemble...

[0029] Example 3 Cut a silk fabric with a size of 1 cm x 1 cm, soak it in dilute NaOH solution for 30 min, take it out and rinse it with deionized water several times, dry it at room temperature, and set aside; weigh 1 g of terephthalic acid, dihydrogen phosphate Sodium 0.35 g and treated silk fabrics were put into deionized water, stirred for 1 hour, rinsed, pressed, prebaked at 70°C for 5 minutes, and baked at 140°C for 3 minutes to obtain terephthalic acid grafted silk fabrics, Then put it in a 20 mL hydrothermal kettle with deionized water as the medium, and add terephthalic acid and EuCl 3 ×6H 2 O and TbCl 3 ×6H 2 The mixed rare earth salt of O (the ratio is 1:2), the molar ratio of acid to total rare earth is 4:1, and the total molar number of rare earth salt remains unchanged. Rinse repeatedly with deionized water and dry at room temperature to prepare silk fabrics with gradient fluorescent colors, the surface of which is a MOFs crystalline material assembled with mi...
