Patent ID: 8641817

Claim:
A method of making an attenuating paint from an initial paint, the attenuating paint for attenuating a reflectivity of electromagnetic radiation, the method comprising the steps of: (a) liquefying the initial paint with a solvent to make a liquefied paint, the solvent being in an amount less than 20% of an amount of the initial paint and corresponding to a type of the initial paint, the initial paint comprising a dielectric constant ∈ r ; (b) adding amorphous metallic microwires to the liquefied paint in a proportion X to the liquefied paint make a mixed paint having integrated microwires, the amorphous metallic microwires having a length l and a metallic core with a core diameter d c ; (c) beating the mixed paint with a mixing rod at a speed of less than 2500 revolutions per minute to integrate the amorphous metallic microwires to make the attenuating paint; wherein a maximum attenuation frequency of the reflectivity of the electromagnetic radiation having a range which is determined by the length l and the core diameter d c of each of the microwires, by a proportion X of the microwires in the attenuating paint, and by the dielectric constant ∈ r of the initial paint.
