Thermally conductive electromagnetic absorbing material

The present disclosure provides a thermally conductive electromagnetic absorbing material comprising a plurality of particles dispersed in a binder. The plurality of particles may have a particle size distribution having at least three peaks, wherein at least a majority of the particles within a half-width at a half-maximum of one of the at least three peaks, rather than other peaks, are at least partially coated with an electromagnetic absorbing coating. The plurality of particles may include a plurality of first particles and second particles, where the total number of the first particles is at most 1% of the total number of the first particles and the second particles, and where the first particles are more electromagnetic absorbing than the second particles. Films, moldings, and systems including the thermally conductive electromagnetic absorbing material are described. 本公开提供了一种导热电磁吸收材料，该导热电磁吸收材料包括分散在粘结剂中的多个颗粒。该多个颗粒可具有具有至少三个峰的粒度分布，其中在该至少三个峰中的一个峰(而不是其他峰)的半最大值处的半宽度内的至少大多数颗粒至少部分涂覆有电磁吸收涂层。该多个颗粒可包括多个第一颗粒和第二颗粒，
