Title:
MATCHED-TYPE ELECTROMAGNETIC WAVE ABSORBER
Document Type and Number:
WIPO Patent Application WO/2017/090623
Kind Code:
A1
Abstract:
[Problem] Matched-type electromagnetic wave absorbers having the shape of a sheet could obtain magnetic wave absorption performance while being relatively thin, but there was the problem in particular that, when exposed to high temperatures, change in dimensions of the electromagnetic wave absorbing layer (a resin composition layer) greatly affected electromagnetic wave absorption performance. [Solution] In the cured product of a resin composition having an acrylic polymerizable resin and a polymerization initiator, by laminating a resin composition layer, in which a filler with an aspect ratio of 5 or greater and a filler with an aspect ratio of less than 5 are fixed in a dispersed manner, with an electromagnetic wave reflective layer, it is possible to provide a matched electromagnetic wave absorber that has good heat resistant dimensional stability and good electromagnetic wave absorption performance.
