Abstract
The present disclosure provides a light-absorbing heat-shielding film that achieves usually incompatible characteristics of absorbing visible light and near-infrared rays and emitting less far-infrared rays. The present disclosure provides a light-absorbing heat-shielding film including: a metal layer including fine irregularities, wherein an average height of the fine irregularities is 100 nm or more and 1000 nm or less.
Claims18
A light-absorbing heat-shielding film comprising:
- a metal layer including fine irregularities, wherein
- an average height of the fine irregularities is 100 nm or more and 1000 nm or less.
A method of producing a light-absorbing heat-shielding film, comprising:
- a first step of forming a fine irregular shape of a metal oxide;
- and
- a second step of forming a metal layer on the fine irregular shape of the metal oxide.
A method of producing a light-absorbing heat-shielding member, comprising:
- a first step of forming a fine irregular shape of a metal oxide;
- a second step of forming a metal layer on the fine irregular shape of the metal oxide;
- and
- a third step of bonding a substrate to a surface of the metal layer opposite to the fine irregular shape of the metal oxide.
