A team of Chinese scientists has developed a new polymer material that is thin and super strong. In tests, a piece of adhesive measuring 2.5 by 1.3 cm was able to tow a car weighing 2.1 tonnes. This was reported by
China Daily, a partner of TV BRICS.
Researchers at Zhejiang University conducted the study, inspired by ancient weaving techniques. They interlaced flexible and rigid polymer chains at the molecular level, creating an exceptionally strong material.
Specialists developed a method of “weaving” the chains, using flexible polyurethane chains as the base and rigid epoxy resin chains as the weft (threads running perpendicular to the warp) to create a durable product.
When applied as an adhesive, the material demonstrated shear strength in overlapping joints twice as high as that of other materials.
The scientists’ discovery will be a step towards the development of new materials with customised properties for a wide range of industrial applications.
