They were also able to get the material to wick moisture and sweat away from the body, using tiny pores.
Cui says the next step is to make the material softer, like a comfortable shirt.
"If you touch it, it kind of files close to a regular textile," he said. "We are in development of woven nanomaterial that will feel lighter. This is under research right now and we have some promising data."
Here's a look at how it works:
Svetlana Boriskina, a research scientist at the Massachusetts Institute of Technology's department of mechanical engineering, said the new material holds a lot of promise.

"It's an important milestone, because they showed you can combine several properties, wicking, breathability and new property of IR transparency all in one," said Boriskina, who is working on developing a similar super-cool cloth.
But she agreed there are still some challenges, namely making it both comfortable and getting the material to be able to handle dyes so the cloth can be manufactured in different colors.
"Ideally if it works out, it would look like any other clothes," Boriskina said. "You wouldn't be able to tell the difference. That's what great about this technology. You don't need wiring, coolpacks or anything else on your body."
