The team of scientists from the Institute of Technical Chemistry of the Ural Branch of the Russian Academy of Sciences (branch of the Perm Federal Research Centre of UB RAS) and the Ural Federal University created a composite polymer material. The new composite is made from recycled materials and has unique properties. It reflects electromagnetic waves. It is suitable for wireless systems, including radar and satellite communications systems. Such a composite (actually a plastic) can be used to make housing for devices such as smartphones. It will allow them to reduce their electromagnetic radiation. The description of the new material is published in the journal Diamond and Related Materials.
"It is extremely important that we have been able to create a new composite material from virtually recycled raw materials. The basis of the material is chopped carbon fibers, which we extracted from carbon plastics. In addition, the composition of the composite includes magnetite (it is the magnetic nanoparticles) synthesized in our laboratory. Our work can increase the attractiveness of carbon plastics processing due to the use of secondary extracted carbon fibers in the expensive technologies," says Svetlana Astafieva, the co-author of the development, the Head of the Laboratory of Structural-Chemical Modification of Polymers of the Institute of Technical Chemistry of UB RAS.
