China creates chameleon-like camouflage for military, other uses

/ 10:14 AM December 06, 2024

Chinese researchers have developed camouflage that switches colors in response to its surroundings, similar to a chameleon.

They said this technology makes an individual appear “effectively invisible” when applied to clothing.

The South China Morning Post noted this breakthrough could have significant architectural and military possibilities.

How does this advanced camouflage work?

University of Electronics Science and Technology of China researcher Wang Dongsheng and his colleagues created this technology.

Interesting Engineering says the new material uses a combination of donor-acceptor Stenhouse adducts (DASAs) and organic dyes to change color.

“The SAP materials are in the primary black state under dark and spontaneously switch to another color upon triggering by transmitted and reflected light in the background,” the researchers wrote.

The researchers tested the material by placing a transparent container of SAP solution in colored acrylic boxes.

In response, the SAP solution changed color to match the surrounding acrylic box. 

Next, the scientists placed a SAP solution-filled container in environments with matching colors.

The solution adapted its color to blend seamlessly with the surroundings within 30 to 80 seconds. 

The researchers then extended SAP technology’s applications to coatings that apply to different surfaces. 

Moreover, the material can function accurately in different temperature settings from -20°C to 70°C (-4°F to 158°F).

Indian news outlet Business Standard reports the material’s limitations. For example, it struggles to mimic purple and blue.

Consequently, Wang and his team told SCMP they will add more photochromatic molecules to “achieve finer distinctions in color and faster changing speed.”

Nevertheless, SAP materials have huge potential in architecture, fashion, and military camouflage. 

It’s unprecedented adaptability and consistent performance in varying temperatures open numerous possibilities.

For example, this camouflage could enable Chinese soldiers to disappear in plain sight. Also, future apparel may shift and evolve with their surroundings.
