Title:
ELECTROMAGNETIC WAVE-ABSORBING PARTICLE DISPERSION AND ELECTROMAGNETIC WAVE-ABSORBING TRANSPARENT LAMINATED SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2019/031242
Kind Code:
A1
Abstract:
Provided is an electromagnetic wave-absorbing particle dispersion that is characterized by: containing at least electromagnetic wave-absorbing particles and a thermoplastic resin; the electromagnetic wave-absorbing particles containing a hexagonal tungsten bronze having an oxygen deficiency, the tungsten bronze being 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); and the oxygen vacancy concentration NV in the electromagnetic wave-absorbing particles being 4.3×1014-8.0×1021 cm-3.
