Electromagnetic radiation absorbers and modulators comprising polyaniline

摘要

A method is provided for absorbing electromagnetic radiation using a polyaniline composition, wherein the radiation is infrared, visible light, ultraviolet, radar, or microwave radiation. Also provided is a method for reducing the detectability by radar of an object by increasing the absorption of radar waves and thereby decrease the reflection of the radar waves by applying to the object a polyaniline composition or a partially protonated salt thereof.
