It may seem like something out of a sci-fi film, but clothing that can cool the wearer on demand might become a reality.

A film made of tiny carbon nanotubes (CNT) has a combination of thermal, electrical and physical properties that make it an appealing candidate for next-generation smart fabrics. A North Carolina State University study found that it can be used to develop clothes that can cool the person wearing it. According to one author of the study, CNTs have properties that would allow heat to be drawn away from the body when an external source of current is applied.
