The raw material of the artificial cotton used below was cotton linters, which had dimensions of 30mm × 30 mm.
The preparation method of the palladium-containing plating solution comprises the following steps: to 100mL of distilled water were added 0.2g of palladium chloride, 4.1g of disodium ethylenediaminetetraacetate, 19.8mL of aqueous ammonia, and 0.56mL of hydrazine hydrate in this order.
Example 1
The embodiment relates to a preparation method of a conductive fabric, which comprises the following steps:
step one, soaking the artificial cotton in 0.4 percent chloroauric acid solution for 4 hours, cleaning the artificial cotton for more than three times by using distilled water, and then adding 0.1mol/L NaBH4Reducing the solution for 5 minutes, and finally cleaning the solution for more than three times by using distilled water;
and step two, soaking the artificial cotton attached with the gold seeds in a palladium-containing plating solution for 3 hours to grow palladium nano particles in situ, and then washing the fabric with distilled water for more than three times to obtain the cotton fiber-palladium nano particle composite conductive fabric.
Through a resistivity test, the sheet resistance of the conductive fabric prepared in the embodiment is 8 Ω. As shown in fig. 1, under an optical microscope, it can be clearly seen that palladium metal particles on the surface of the fiber are agglomerated into a metal film and have metallic luster; as shown in fig. 2 and 3, the palladium particles are adhered to the surface of the fiber under a scanning electron microscope, and are in a pyramid shape. Because the soaking time is longer, the size and the number of the palladium particles in the fibers are increased, the palladium particles on the surfaces of the fibers are agglomerated into a continuous metal film, and the cloth is changed from a non-conductive state to a conductive state.
Example 2
The embodiment relates to a preparation method of a conductive fabric, which comprises the following steps:
step one, soaking the artificial cotton in 0.4 percent chloroauric acid solution for 4 hours, cleaning the artificial cotton for more than three times by using distilled water, and then adding 0.1mol/L NaBH4Reducing the solution for 5 minutes, and finally cleaning the solution for more than three times by using distilled water;

The sheet resistances of the conductive fabrics prepared in example 2 and example 3 were 15 Ω and 10 Ω, respectively, according to the resistivity test. Along with the extension of the soaking time of the fabric in the plating solution, the number of metal particles on the surface of the fiber is increased, the size of the metal particles is also increased, and the resistivity is reduced.
