Abstract

Methods for shielding an object from electromagnetic waves (e.g., microwaves, radar waves, IR waves, visible light waves, and UV waves) are described which entail interposing a layer of a polyaniline compn. or a polyaniline salt between a source of the electromagnetic waves and the object to be shielded. Methods of changing the absorption by a polyaniline compn. of electromagnetic radiation by modifying the chem. structure and crystallinog. order of the polyaniline compn. are discussed.
