Imagine wearing clothes that could make you blend seamlessly into your surroundings, just like a chameleon or an octopus. New research published in the journal Science Advances just turned this concept from science fiction to science fact.
The new material is able to adapt its appearance to its environment without the need for clunky electronics or high-tech devices using self-adaptive photochromism (SAP).
The SAP material is made of special organic dyes and molecules called donor-acceptor Stenhouse adducts (DASAs).
When exposed to light, the molecules in SAP rearrange their structure.
This process changes how the material absorbs and reflects light, resulting in a colour shift that matches the surroundings.
It’s a bit like a synthetic version of a chameleon’s skin, but instead of specialized colour-changing cells, SAP relies on a chemical reaction triggered by light.
In the study, the researchers tested this material in several scenarios to showcase its abilities:
Colour Matching in Boxes: A translucent container coated with SAP was placed in boxes of different colours - red, green, yellow, and black. In each case, the material adjusted its hue to match the box within seconds.
Blending with Nature: The material was placed near clusters of colourful plants. Whether surrounded by red flowers, green leaves, or yellow blooms, it seamlessly melted into its environment in under a minute.
Current camouflage systems rely on external power sources and complicated electronics, however these new SAP materials only need light to activate the camouflage effect.
As they are much cheaper than traditional systems and can be sprayed onto surfaces as a coating, the potential uses for this technology are huge and we could all be walking around with our own invisibility cloak very soon.
