Researchers develop chalk-based coating to cool textiles

Researchers from the University of Massachusetts have created a chalk-based coating for textiles that can reduce air temperatures beneath the fabric by up to 8°F, offering a sustainable solution for cooling without the need for energy consumption.

This innovative coating is made from calcium carbonate and barium sulfate, materials that effectively reflect UV and near-infrared light, thereby enhancing comfort in hot climates. Simulation tests have confirmed the durability of this coating, making it a promising option for regions with high temperatures.

Existing textiles that reflect the sun’s rays or dissipate heat often require specialized fibers or complex manufacturing processes. However, the newly developed chalk-based coating provides a simpler, more accessible solution. It can be applied to nearly any commercially available fabric, transforming it into a material that helps keep people cool.

Evan D. Patamia, a graduate student at the University of Massachusetts Amherst, says, “Our coating offers a significant cooling effect, which could be a valuable resource for people struggling to stay cool in extremely hot environments.”

Trisha L. Andrew, a chemist and materials scientist collaborating with Patamia, explains the science behind the innovation: “When you walk into sunlight, your body and clothing absorb ultraviolet and near-infrared light, causing you to heat up. Our technique uniquely converts almost any fabric into a cooling material without requiring power input.”
