China makes shining example of technology
Fancy a party dress that will shine like a star or a tuxedo that can change colours? A new material developed by Chinese scientists may help you get just that.
Beijing: Fancy a party dress that will shine like a star or a tuxedo that can change colours? A new material developed by Chinese scientists may help you get just that.
Peng Huisheng and his colleagues from the Shanghai-based Fudan University plan to make you carry countless number of batteries to make your garment shine, only that the cells are fiber-shaped so they can be woven into fabric, Xinhua news agency reported citing the latest issue of Nature Photonics.
The light, flexible, fibre polymer light-emitting electrochemical cells (PLEC) are made by wrapping metal wire cathode in a carbon nanotube sheet that is the anode. They activate an electroluminescent polymer layer in between, which emits light.
PLECs are powered by a low voltage, boast high efficiency and are suitable for mass production, said Zhang Zhitao, one of the article's authors.
The materials can display various colours, and fabric made with them can change colours by adjusting the brightness ratio.
In a peer review article, material scientists Enrique Orti and Henk Bolink say the technology was "a major step forward in the preparation of light-emitting fibers that suit integration with woven fabrics", although improvements are still needed.
