ELECTROMAGNETIC WAVE ABSORBER AND MANUFACTURING METHOD THEREOF
PROBLEM TO BE SOLVED: To provide an electromagnetic wave absorber and a manufacturing method thereof which are excellent in heat resistance and hardly cause periodic fluctuation of electromagnetic wave absorption against frequency change.SOLUTION: In an electromagnetic wave absorber according to the present invention, an activated layers of an activated particles each of which an inner core particle having at least a surface made of silicic acid or a silicate and an activation layer which forms an outer shell of the inner core particle and is mechanochemically activated are bonded together by dehydration condensation to form a solidified body, and activated carbon nanotubes are dispersed in the activated layer.SELECTED DRAWING: Figure 1
【課題】耐熱性に優れ、周波数の変化に対する電磁波吸収の周期的な変動が生じ難い電磁波吸収体及びその製造方法を提供する。【解決手段】本発明の電磁波吸収体は、少なくとも表面がケイ酸又はケイ酸塩からなる内核粒子と、該内核粒子の外殻をなしメカノケミカル的に活性化された活性化層と、を有する活性化粒子の該活性化層どうしが脱水縮合によって結合して固化体をなし、該結合した該活性化層にはカーボンナノチューブが分散されている。【選択図】図１
