According to foreign media reports, Duke University engineers are layering graphite to create a unique and versatile material, and scientists point out that the new material can even be used to develop Artificial muscles.
It is understood that due to different environments, graphite is particularly easy to "twist", showing positive or negative characteristics, so it is difficult for scientists to control the substance and use its characteristics.
Xuanhe Zhao, an engineer and assistant professor at the Pratt School of Engineering at Duke University, said: "If you want to crumple a piece of ordinary paper, you can smooth it out soon. But graphite is more like damp Paper towels are extremely thin and sticky. Once crumpled, they are difficult to smooth. We have developed a solution to this problem, which can control and smooth the distortion of large areas of graphite film. "
Researcher Jianfeng Zang from Xuanhe Zhao's research team said: "Our method can also explore the unprecedented characteristics and functions of graphite."
In addition, these engineers use different polymer membranes to layer graphite to create a "soft" material similar to muscle, which can also be stretched according to different requirements. When the graphite contacts the power supply, the artificial muscle can extend a certain area, and when the power supply is cut off, the muscle returns to a relaxed state. Through the adjustment of the voltage, the degree of expansion and contraction of the artificial muscle can be controlled, and the degree of expansion and contraction can exceed 100%.
Jianfeng Zang said: "It is true that artificial muscles can be greatly deformed by twisting and smoothing graphite."
It is reported that scientists promise that artificial muscles will improve the quality of life of millions of people with disabilities.
