IR radiations from the sun increases the internal temperature of the buildings when transmitted through glass windows. To reduce this elevated temperature, air conditioning systems are used that consume a large share of total energy expenditure which harms the energy footprints of the ecosystem. To combat this problem IR radiation must be blocked, thereby not affecting visible light transmission. Conductive metal oxides have been found effective in blocking IR radiation. In this work, antimony-doped tin oxide sub-20 nm particles were synthesized by co-precipitation method. The synthesized nanoparticles were homogenously dispersed within polyurethane latex that later encrusted onto polyester textiles for IR-blocking properties. The coated fabrics simultaneously achieve excellent shielding of NIR (90 %) and high transmittance of visible light (80 %), which makes them an ideal material to alleviate the current building energy consumption issues that correspond to a greater than 20 % saving on indoor cooling/heating. These fabrics equally bear other special features such as strength, self-cleaning, and photoactivity required by such furnishing clothes. The developed IR blocking fabric will ensure a sustainable future with a less adverse load on the energy footprints of the ecosystem and thus make human settlements resilient and tackle the impacts of climate change.
