Claim 5:
6. The method according to claim 1, wherein in step (5), the carbon nanotubes comprise multi-walled carbon nanotubes, single-walled carbon nanotubes, carbon nanotube bundles, or a combination thereof; a mass ratio of silver nitrate, pyrrole, and the aramid fiber bundles with two-layered coatings of carbon nanotubes and silver nanoparticles is (0.2-4):(0.1-2):(0.1-1); a reaction of the aramid fiber bundles with two-layered coatings of carbon nanotubes and silver nanoparticles, the aqueous solution containing pyrrole and the silver nitrate aqueous solution is carried out at room temperature for 5 to 48 hours; after the reaction is completed, the aramid fiber bundles with two-layered coatings of carbon nanotubes and silver nanoparticles are taken out, washed, and dried to obtain the aramid fiber bundles with three-layered coatings of polypyrrole, carbon nanotubes, and silver nanoparticles.
