New Progress In Smart Fiber Research

Like the chameleon, it can automatically change color according to the surrounding environment. 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 reporter learned from the school of materials, Donghua University, that the research team of the Institute has made new progress in the field of intelligent fiber research. These seemingly high-tech technologies are getting closer and closer to our lives with the increasing functionality and intelligence of fiber materials.

Discolourable clothes or will be free to "change".

Popularly speaking, smart fiber is the fiber that can take the initiative to perceive and respond to the external environment.

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, the research group of Professor Wang Hongzhi of Materials Institute has realized the self discoloration of fiber under the electricity 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 too

The modification of fiber materials by scientific means is likely to make fibers more "smart" and "more intimate" and make a variety of magical changes according to people's work and life needs.

"Taking discolored fibers, this not only helps 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.

Spinning can be made graphene solar cells can also be woven.

The emergence of Google glasses has opened up a trend of wearable smart equipment. But today, energy supply is still a major problem in the development of intelligent equipment. For example, the Google eyeglasses should always be attached to lithium batteries which are heavy and limited in use time.

This problem is equally difficult in the development of smart clothing.

How to make the energy supply of smart clothing lighter and longer? The research experts of the Institute of materials at Donghua University think of starting from the "root" of fiber. If we can enhance the electrical conductivity and storage performance of the fiber, and at the same time enable it to have good weaving ability, and let the energy supply device become part of the clothes itself, can not we realize the lightweight of the smart clothing and guarantee the energy supply to the maximum extent?

For this reason,

Personnel targeting is known as the "super material" of graphene, which can trigger new changes in materials science.

The Yangtze River scholar innovation team of the Ministry of education, led by the dean of the school of materials and Professor Zhu Meifang, Yangtze River scholar, is currently using the wet spinning method to continuously produce 1000 kilometre of graphene fibers.

This kind of fiber not only has the highest conductivity of the same kind of product, but also has the highest international strength. It can easily be woven into the desired fabric type and maintain 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 pmission at the same time.

In addition, researchers have 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 pform solar energy into electricity by ourselves".

Chen Zhigang also admitted that despite the advantages of knitted flexible solar cells, such as knitted, low carbon, environmental protection, strong endurance and light quality, it is in line with the requirements of smart clothing. However, due to the relatively high cost and the efficiency of energy conversion to be improved, it is still time for these batteries to fly into the common people's home from the laboratory.
