This material could camouflage objects from infrared cameras
The coating flouts the typical trend of hotter objects radiating more light

When heated from about 100° to 140° Celsius (left to right), a normal material (top) radiates more brightly, and an infrared camera registers a higher temperature (brighter colors). But a special coating (bottom) fools the camera into detecting little temperature change.
