Scientists have developed lightweight fibers with both strength and toughness.

A thin horse has fat hooves, but a son steals from his father. Hello, everyone, this is the deep space editor and the deep space player. It's a nice day today, so it's suitable for reading the latest information and relaxing. Get the melon seeds bench ready and let's go and have a look.

When it comes to man-made fibers, they are usually strong and tough, but they can't have both. However, a new material developed by scientists at Reuters University is said to have both characteristics.

In short, strength is the ability to bear without permanent deformation, and toughness is the ability to bear without fracture. It is reported that this new fiber not only has these two characteristics, but also is very light and completely recyclable.

Each fiber is about the width of a hair and consists of as many as 4000 smaller fibers, which are made of an industrial polymer called polyacrylonitrile. These smaller fibers are called fibrils and are produced by electrostatic spinning. A small amount of polyethylene glycol azide is used to longitudinally bond them together.

The result is that a fiber is composed of many connected fibrils. Stretch and heat the fiber, then cool it for a few hours-still in the stretched state. It is said that the quality of the finished product is similar to that of spider silk. A short fiber can be used to repeatedly lift a substance weighing 30 grams without breaking or permanently stretching. Now researchers hope that once the technology is further developed, "multi-fiber polyacrylonitrile fiber" can be applied to textile, aerospace or medical fields.

Professor Andreas Greiner, the chief scientist, said, "We can be sure that our research results have opened the door for new forward-looking materials. These are expected to be applied to industry in the near future. In the field of polymer science, our fibers will be able to provide valuable services for the further research and development of high-performance functional materials. "

The research paper was recently published in the journal Science. Scientists from Martin Luther Haller wittenberg University, Aachen University of Technology, Julich Research Center, Flawn Hof Institute of Materials and Systems Microstructure, Jiangxi Normal University in China and Swiss Federal Institute of Technology in Zurich also participated in this research.
