Colour-changing textiles for temperature regulation
A groundbreaking textile that changes colour to regulate temperature might just transform smart clothing and outdoor gear. Developed using thermochromic microcapsules, this material absorbs sunlight to warm up in cold temperatures and reflects it to cool down when it’s hot—all without requiring an external power source. The fabric has already been tested in jackets and tents, showing the ability to maintain a comfortable temperature range in various climates. It’s even scalable, with production achieved in rolls as large as 0.8 by 10 metres, and adaptable to surfaces like wood, metal, and paper.
This innovation has wide-reaching potential, from eco-friendly clothing to efficient cooling systems for buildings. The use of barium sulfate and reduced graphene oxide enhances durability and effectiveness, ensuring the material is sustainable and long-lasting. Experts see commercial applications on the horizon, though safety and environmental testing are key steps before broader adoption. Could this fabric be the future of adaptive, energy-efficient technology?
