Plastic-wrap inspired fabric could keep us cool in the future

What should you wear to keep cool on a hot day? One word: plastics.

A form of polyethylene — the common plastic that makes up ClingWrap — is a promising candidate for a textile that prevents us from overheating, researchers say. Hopefully, it won’t look like those PVC bodysuits that pop up every Halloween.

Many researchers are trying to create cooling fabrics, from cloth inspired by squid skin to electroactive textiles. But the team led by Yi Cui, a materials scientist at Stanford University, was inspired by materials that we don’t usually consider for clothing. In a study published today in Science, the team turned a battery component into a textile that lets our body’s natural heat escape better than cotton. The team hasn’t worn the...
