Abstract
Methods, systems, and devices are disclosed for implementing lightning strike protective compositions. In one aspect, a composition for providing protection against electrical discharges (e.g., including lightning strikes) for composite structures includes a binder material capable of dispersing material structures therein and attaching to a surface of a substrate, and a plurality of pigment structures dispersed in the binder material. The pigment structures include a central layer including an electrically conducting material, and outer layers formed on the central layer, in which the outer layers include an optical absorber material or a dielectric material. The composition, when attached to the substrate, is capable of providing electrically conductive paths to transfer electrical current from a multi kiloamp electrical discharge within the composition.
