Fabric coating thwarts detection by night-vision devices

A thin film developed by scientists at the University of California Irvine combines reflection and graphene to make clothing surfaces indistinguishable from surroundings under infrared light, rendering those wearing such materials effectively invisible to night-vision devices, according to this article. The film, inspired by the camouflaging ability of squid, can also be adjusted in the presence of humidity or acetic acid to reflect infrared light differently.
