Flexible Material Shows Potential for Use in Materials to Heat, Cool

Researchers at North Carolina State University have developed a film made of tiny carbon nanotubes which has a combination of thermal, electrical, and physical properties that make it an appealing candidate for next-generation smart fabrics. The researchers were able to optimize the thermal and electrical properties of the material, allowing the material to retain its desirable properties even when exposed to air for many weeks. This material may enable the development of clothing that can heat or cool the wearer on demand.
