Researchers from the Perm National Research Polytechnic University (PNIPU) have developed a durable and environmentally friendly coating based on thermally expanded graphite. The press service of the scientific institution told socialbites.ca that the device is designed to absorb unwanted electromagnetic waves.
According to scientists, this material will be in demand both in the defense industry and in civilian life.
The thermally expanded graphite in the composite base is a highly porous, powdery material. Physical and mechanical properties, as well as chemical and thermal stability, allow it to be pressed into products of various shapes and densities. The ability of graphite to scatter infrared radiation was discovered relatively recently, so it had not been used for these purposes before.
“We offer a material with high adhesion [клейкость] It adapts very well to various fabric types (cotton, fiberglass, acetate, carbon). We conducted the testing using a thermal camera with images that clearly demonstrate the effectiveness of the shielding. Fabrics coated with a protective mixture have the ability to dissipate heat and protect from electromagnetic radiation. The thickness of the fabric layer is only 0.5 mm, student of the Department of Polymer Materials and Powder Technology of PNIPU Andrey Myakshin told Gazeta.ru.
In addition to using the material to conceal military equipment, it can also be used to make protective cases for phones, smartwatches and other devices in situations where it is necessary to conceal the device’s location.
Previously in Russia was created Method of biological purification of wastewater from toxic phenol.
