Abstract

Abstract: Significant progress has been made in transparent thermal insulation coating by various effective materials in recent years. More recently, Low-E coating, as a high reflection coating, has been applied in many buildings, but the coating would cause light pollution due to visible light reflection, resulting in prohibiting use in many countries. Hence, a novel transparent thermal insulation coating based on ATO/Black TiO2 is proposed in this paper. The bilayer coating exhibited a high near infrared light blocking rate of 86%, and the visible light transmittance was about 62%. Meanwhile, the structural thin films had excellent photocatalytic property, which could degrade approximately by 45% of methylene blue in 3 hours under fluorescent lamp. The double layered coating had shown a water contact angle of lower than 5° after activating. Overall, these structural films show a great potential for applications in energy conservation windows.
