Example Embodiment
[0028] Example 1
[0029] (1) Preparation of conductive components: completely dissolve polyvinyl alcohol in water, prepare a 1wt% polyvinyl alcohol aqueous solution, add 100 mg of silver nanowires, and stir evenly to obtain a conductive polymer composed of 1wt% silver nanowires. component;
[0030] (2) Soak the washed 5cm×5cm×250μm pure cotton fabric in the conductive component obtained in step (1) for 3s, dry it, and repeat the soaking and drying for 10 times, so that the surface of the pure cotton fabric is loaded with enough silver nanometers. Wire;
[0031] (3) Prepare a 1wt% glutaraldehyde solution, adjust the pH to 1 with 1M hydrochloric acid, and the conductive pure cotton fabric prepared in step (2) (see figure 1 ) spray 1 mL of glutaraldehyde solution on the surface, put it in an oven, and react at 80 °C for 1 h, so that the polyvinyl alcohol in the conductive component and the surface of the pure cotton fabric are fully cross-linked. Wash thoroughly with water to...

[0034] Example 2
[0035] (1) Preparation of conductive components: completely dissolve polyvinyl alcohol in water, prepare a 1wt% polyvinyl alcohol aqueous solution, add 80mg silver nanowires, stir evenly, and obtain a polymer composed of 0.8wt% silver nanowires. conductive components;
[0036] (2) Soak the washed 5cm×5cm×250μm chitosan fabric in the conductive component obtained in step (1) for 3s, dry it, repeat soaking and drying 8 times, so that the surface of the chitosan fabric can be loaded with enough silver nanowires;
[0037] (3) Prepare a 1wt% glutaraldehyde solution, adjust the pH to 7 with 1M sodium hydroxide, spray 2 mL of glutaraldehyde solution on the surface of the conductive chitosan fabric obtained in step (2), and put it in an oven , and reacted at 60°C for 1 h to fully cross-link the surface of the polyvinyl alcohol and chitosan fabrics in the conductive components. Wash thoroughly with water to remove unreacted glutaraldehyde and polyvinyl alcohol on ...
Example Embodiment
[0039] Example 3
[0040](1) Preparation of conductive components: completely dissolve polyethyleneimine in ethanol, prepare a 10wt% polyethyleneimine ethanol solution, add 100mg silver nanowires, stir evenly, and obtain a polymer and 1wt% silver nanowires. The conductive component of the wire;
[0041] (2) Soak the washed 5cm×5cm×250μm chitosan fabric in the conductive component obtained in step (1) for 10s, dry it, repeat soaking and drying 5 times, so that the surface of the pure cotton fabric is loaded with enough silver Nanowires;
[0042] (3) Prepare 0.5wt% glutaraldehyde solution, adjust the pH to 7 with 1M hydrochloric acid, spray 5 mL of glutaraldehyde solution on the surface of the conductive chitosan fabric obtained in step (2), put it in an oven, The reaction was carried out at 80°C for 1 h, so that the surface of the polyethyleneimine in the conductive component and the chitosan fabric were sufficiently cross-linked. Wash thoroughly with water to remove unreact...
