Infrared Blocking Materials: A Science-Based Approach to Transparent Heat Insulation
Infrared Blocking Materials: A Science-Based Approach to Transparent Heat Insulation 紅外線阻隔材料：透明隔熱應用中的科學化材料方案 Why Infrared Blocking Matters In modern buildings, vehicles, and functional films, one of the key challenges is how to reduce heat from sunlight without sacrificing transparency. Sunlight contains ultraviolet, visible, and near-infrared radiation. Recent studies on energy-saving coatings point out that near-infrared radiation accounts for a significant portion of solar heat, and ordinary glass lacks spectral selectivity because it allows both visible light and near-infrared light to pass through. Therefore, transparent heat-insulation materials need to selectively block near-infrared radiation while maintaining high visible light transmittance. This is exactly the
