Document Type and Number:
WIPO Patent Application WO/2022/163655
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an air gap layer in which a bonding agent or an adhesive does not readily penetrate into an air gap. In order to achieve the above-described purpose, an air gap layer according to the present invention is formed by chemically bonding particles with each other, and is characterized in that: the void fraction of the air gap layer is 35% by volume or more; the particles are inorganic-organic composite particles, each of which is obtained by bonding an organic group to an inorganic compound; the organic group comprises an R1 group that is a linear or branched alkyl group, and an R2 group that contains a carbon-carbon unsaturated bond; and the molar proportion of the R2 group relative to the total of the R1 group and the R2 group is 1-30% by mole.
