The invention discloses a self-dedusting monitoring camera lens and a preparation method thereof. Meanwhile, the carbon nano tube is modified by acid liquor, thionyl chloride and octadecylamine through a specific preparation method in sequence, and the size of the prepared modified carbon nano tube coarse structure is smaller than the wavelength of visible light by more than 100nm, so that Mie scattering of light can be avoided, and high transparency can be obtained. Two groups of electrode patches are adhered to the edges of the two sides of the lens, which do not influence the shooting range of the camera, and dust is completely removed from the surface of the lens by using a three-phase traveling wave electric field. |
