Fudan University, China “chameleon Fiber” – Fiber, Carbon Nanotubes – The Chemical

“Chameleon fiber,” the research laboratory of Fudan University in China, was born! September 13, world-class academic journals “Nature? Nanotechnology” published on this results, instantly attracted widespread attention at home and abroad.

This “chameleon fiber,” From Molecular Engineering of Polymers, Fudan University Education Ministry Key Laboratory of Advanced Materials Laboratory, the research team led by Professor Peng Huisheng hand. It can be with the flow through the “body” of the current changes in the color change. In fact, behind this amazing invention, but also hide another invention?? “Carbon fiber”, which also from Peng Huisheng research.

“Beijing Science and Technology News”: how concerned you are from the “carbon fiber”?

Peng Huisheng: long ago, scientists around the world, extensive research on carbon nanotubes, because of its light weight, high hardness, conductivity and strong.

Boeing and the U.S. military is willing to spend hundreds of millions of dollars manufacturing high mechanical strength, electrical conductivity and strong fibers. Boeing said in a conference, new materials, should carbon fiber base will be used in future Boeing aircraft.

I was born in polymer materials science, carbon nanotubes have not previously done, but such materials have a certain understanding, that the relevant departments of the United States is very interested in carbon nanotubes, I will to the United States Energy National Laboratory for the Department of LosAlamos funds to carry out the research. In 2006, I passed the defense, had the honor to enter into the lab.

“Beijing Science and Technology News”: How do you invent a new material?
Penghui Sheng: I will be synthetic polymer material and carbon nanotubes to form the new composite fiber, which combines the advantages of both, very soft, very light, strength, stable nature.

On the aircraft, the type of composite material is nothing better. Currently, the new Boeing 787 out of the main composition is carbon fiber, while the density of carbon fiber carbon fiber is only 1 / 10, but the higher strength and hardness. Experts predict that carbon nanotubes could replace the fiber carbon fiber.

“Beijing Science and Technology News”: How did you find that the color of carbon fiber?

Peng Huisheng: In 2008, I came back, and try to add more in the carbon nanotubes of different polymer materials. I chose a typical conducting polymers?? Poly diacetylene. It formed a blue and carbon nanotube composite fibers.

Once we inadvertently transfer a large number of the current, suddenly, materials become red. This caused us great attention. We change the structure of polymer diacetylene found that in addition to red, materials can also be turned into brown, orange, yellow; and turn off the current, the color will change back.

“Beijing Science and Technology News”: The new material will change our lives what?
Peng Huisheng: Currently, we study how the carbon fiber used in solar cells, so that heavy huge solar panels can be rolled up like a mat carrying the same. In Auto Manufacturing, particularly cars, this material may be replacing the existing sports car Plastic Shell, so that more light sports car, you can save more fuel consumption, durability, impact resistance, even more beautiful. Neon color changing fiber can be a good material, but also can be applied to Electronic Safety switches, color devices, smart windows, sensitive devices and other fields. “Chameleon fiber,” the research laboratory of Fudan University in China, was born! September 13, international first-class academic journals “Nature? Nano-technology” on the results published this, instantly attracted widespread attention at home and abroad.
