New Progress In Intelligent Fiber Research Of Donghua University

Clothes can be automatically discolourable according to the change of surrounding environment like the chameleon. The insole can automatically generate electricity through the human body during the walk, and the curtains can adjust themselves with the external light intensity. The research team of Donghua University School of materials has made new progress in the field of intelligent fiber research. These seemingly high-tech technologies are increasingly close to our life with the increasing functionality and intelligence of fiber materials.

　　 Intelligence Fiber is popularly said to be able to take the initiative to perceive and respond to the external environment and make relevant reactions. Like clothing, accessories, home textiles and other common people's common objects, if they change their smart fibers, they can generate electricity, shine, heat and discolor. In the State Key Laboratory of fiber material modification, Donghua University, Professor Wang Hongzhi's research team has achieved repeated self discoloration in the electrified environment after repeated experiments. As long as the low voltage stimulus of 2-3v is introduced, the fibers can change the red, yellow and blue color in milliseconds and keep the color for half an hour. Even in the case of twisting, knotting and weaving, the fiber still discoloration. "This can not only help us realize the dream of" neon ", but also has great application value in military camouflage and other fields. I believe that our soldiers will be able to change freely in desert, jungle and sea in a military uniform, Professor Wang Hongzhi said.

How to make the energy supply of smart clothing lighter and longer? The research experts of the Institute of materials at Donghua University want to start with the "root" of fiber, which improves the electrical conductivity and storage performance of the fabric, and enables it to have good knitted properties. They aim at the graphene, which is known as "super material" that can trigger new changes in materials science. Since 2009, it has organized research efforts to tackle problems. The innovation team led by the dean of the Institute of materials and Professor Zhu Meifang, Professor of Yangtze River, has been making great efforts in the research of high value and intelligence of general fiber. This kind of fiber has conductivity. similar The product has the highest value, and its strength is also up to the international leading level. It can be woven into the desired fabric type very easily and maintain the ideal electrical conductivity and strength. The team has strong cooperation with the relevant research teams at home and abroad, and successfully assembled the graphene fiber into a super capacitor. Weaving the capacitor into a fabric will achieve the function of smart clothing's power storage and transmission at the same time.

In addition, the academy has made important breakthroughs in the research and development of "fiber flexible solar cells". According to the Chen Zhigang researcher of the Institute, fiber flexible solar cells have been developed in the laboratory. "Figuratively speaking, in the future, we can use fiber solar cells to weave cloth, and clothes can transform solar energy into electricity by ourselves". Chen Zhigang also admitted that because the cost is relatively high and the efficiency of energy conversion needs to be improved, it is still time for such batteries to fly into the common people's home from the laboratory. "We will stick to this" hard bone ". Insist Unremitting efforts.
