Embodiment 1

[0158] Example 1 Synthesis of TiO by Photocatalytic Reduction 2 Ag nanomaterials

[0159] Will contain 0.1g TiO 2 (P25) 50ml 0.1MAgNO 3 The ethanol solution was irradiated with a 20W ultraviolet lamp under magnetic stirring. The irradiation distance (distance from the lamp to the liquid surface) was 10 cm, and the irradiation time was 2 minutes. Then due to Ag + reduced to Ag 0, the color of the suspension changed from white to brown. The product was collected and washed with deionized water. Finally, it was completely dried at 40 °C.

Embodiment 2

[0160] Example 2 Using DHBPA to modify TiO 2 Ag nanomaterials

[0161] A total of 1.00 g of TiO 2 (P25), TiO 2 The Ag nanomaterials were respectively dispersed into 100ml of an aqueous solution containing 10mg of DHBPA. The mixture was magnetically stirred at room temperature for 10 minutes, and then centrifuged at 8000 rpm for 10 minutes. The solid product was washed thoroughly with deionized water and dried at 40 °C.

Embodiment 3

[0162] Example 3 SFF samples were processed in the following two steps:

[0163] (1) Immerse the SFF sample in 100ml chitosan aqueous solution (containing 0.5g chitosan, 8g BTCA, 3g SHP) at 25°C, and then pad at 90% liquid absorption. Next, the samples were dried at 80°C for 5 minutes and baked in a laboratory oven at 160°C for 3 minutes.

[0164] (2) Chitosan-treated SFF samples, 0.1g DHPBA-modified nanomaterials (respectively TiO 2 and TiO 2 Ag) was placed in 40 ml of deionized water and gently mechanically stirred for 10 minutes. Then extract the SFF sample and at 15kg / cm 2 Padding under pressure. Then, the samples were cured in a laboratory oven at 80 °C for 5 min and washed with deionized water followed by ultrasonic treatment for 5 min to remove unfixed material. Finally, the samples were dried at room temperature.

Abstract

The invention relates to a nano material modified or functionalized silk protein-based material. The nano material is fixed on the main body or the surface of the silk protein-based material. The invention also relates to the preparation method of the nano material modified silk protein-based material.

Description

technical field [0001] The present invention relates to a nanomaterial-modified or functionalized silk protein-based material, wherein the nanomaterial is immobilized in the bulk and / or on the surface of the silk protein-based material, and to the preparation of the nanomaterial-modified Methods for silk protein-based materials. Background technique [0002] In addition to the basic requirements of comfort and fashion, the global trend of the textile industry is to develop and manufacture multifunctional high value-added textile products, such as anti-aging, UV protection effect, antibacterial and self-cleaning ability, etc. In addition, petroleum, one of the most important raw materials for synthetic fibers, will disappear in the future. Considering the impact of synthetic fiber production on the environment, the industrial and consumer markets would rather choose multifunctional natural products than synthetic fibers. Clearly, multifunctional materials based on natural ma...
