Title:
ELECTROMAGNETIC WAVE-ABSORBING TRANSPARENT SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2019/031246
Kind Code:
A1
Abstract:
Provided is an electromagnetic wave-absorbing transparent substrate which includes: a transparent substrate that is a resin substrate or a glass substrate; and a coating layer disposed on at least one surface of the transparent substrate. The coating layer is a layer of a binder resin that includes electromagnetic wave-absorbing particles. The electromagnetic wave-absorbing particles contain a hexagonal tungsten bronze having an oxygen deficiency. The tungsten bronze is represented by general formula MxWO3-y (here, the element M includes at least one element selected from among K, Rb and Cs, 0.15 ≤ x ≤ 0.33, and 0 < y ≤ 0.46). The oxygen vacancy concentration NV in the electromagnetic wave-absorbing particles is 4.3×1014-8.0×1021 cm-3.
