Wouldn’t it be nice if your clothes could keep you as cool as your A/C? This new, durable fabric coating can cool the wearer by up to 15 degrees Fahrenheit without using any additional energy, thanks to special crystals that reflect both infrared and ultraviolet light.

Transcript

This fabric coating could cool the wearer by almost 15 degrees Fahrenheit without using any energy, providing a simple source of relief on a hot summer day.

It’s made from durable and cheap materials. Researchers first laid down a thin layer of a polymer onto the fabric. Then they dipped it into chemical solutions, which grew into a reflective layer of calcium carbonate and barium sulfate crystals.

These crystals reflect visible light, as well as near-infrared and ultraviolet light from the sun while allowing body heat to escape. The treated fabric keeps a wearer up to 15 degrees cooler than untreated fabric, or 7 degrees cooler than ambient air. And it holds up to washing.

This research is being presented at ACS Fall 2024, a meeting of the American Chemical Society.
