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.

Abstract: An electrically conductive adhesive layer includes a plurality of particles dispersed between opposing first and second major surfaces of the electrically conductive adhesive layer. The first and second major surfaces are spaced apart a distance D. The particles are agglomerated so as to form a plurality of substantially continuous layers of particles generally extending along orthogonal first and second directions and arranged along a third direction. Each substantially continuous layer of particles has a length L along the first direction from a first to an opposing second edge of the electrically conductive adhesive layer and a width W along the second direction extending from the first to the second major surface. L/D ≥ 100. At least some of the particles are electrically conductive.

Abstract: A magnetic film includes a plurality of magnetically permeable particles dispersed between opposing first and second major surfaces of the magnetic film. The first and second major surfaces are spaced apart a distance D. The particles are agglomerated so as to form a plurality of substantially continuous layers of particles generally extending along orthogonal first and second directions and arranged along a third direction. Each substantially continuous layer of particles has a length L along the first direction from a first to an opposing second edge of the magnetic film and a width W along the second direction extending from the first to the second major surface.
