The invention relates to a nanometer strip conductive polyaniline compound and a preparation method thereof. In the method, ice crystal is employed as the template, and H4SiW12O40 with a Keggin structure is adopted as a doping acid for adjusting the product form. The mild oxidizing agent ferric nitrate is employed to control the polymerization rate of aniline, and silver nitrate is introduced, isreduced to the metal silver through the anti-induction action of aniline polymerization and can be compounded into a polyaniline product. The method simplifies the complex process of template preparation and removal, saves material and energy, and can produce products with single form and high purity. The polyacid doped polyaniline / silver nanoparticle compound of the invention synchronously introduces polyoxometallate (H4SiW12O40) and silver metallic nanoparticles. Under the synergism of silver nanoparticles and polyacid, the compound of the invention shows good response sensitivity to ultraviolet lights with a wavelength of 365nm, so that the compound is able to be used in devices like light sensors, electric switches and the like.
