Abstract
A thermally conductive electromagnetically absorbing material includes a plurality of particles dispersed in a binder. The plurality of particles can have a particle size distribution having at least three peaks, where at least a majority of particles within a half width at half maximum of one, but not the other ones, of the at least three peaks are at least partially coated with an electromagnetically absorbing coating. The plurality of particles can include pluralities of first and second particles where a total number of the first particles is at most 1% of a total number of the first and second particles and where the first particles are more electromagnetically absorbing than the second particles. Films, molded articles and systems including the thermally conductive electromagnetically absorbing material are described.
