Tomsk State University of Control Systems and Radioelectronics (TUSUR) and the Joint Institute for Nuclear Research (JINR) have started joint work on radiation protection materials. This concerns special fabric for spacesuits and tiles for cladding habitable modules of spacecraft.
The main focus of the Tomsk laboratory is on thermal control coatings. They prevent the spacecraft from overheating in the sun or overcooling in the shade. These compositions are based on inorganic pigments and binding components. To increase radiation resistance, researchers actively use nanotechnology: they modify the structure of materials at the particle level and test new formulations.
To select the most stable materials, TUSUR involves industrial partners and modern equipment. Scientists use infrared spectroscopy, X-ray diffraction analysis, and electron microscopy. Special attention is paid to studying the reflection of light from surfaces in a vacuum — both diffuse and specular. They also model the effects of high-energy ions to understand how the properties of substances change under their impact.
Based on the results of the experiments, compositions with maximum resistance will be selected. Prototypes of protective fabric for spacesuits and tiles for external cladding will be created on their basis. The results of the project are expected to improve the safety of manned flights and extend the service life of space equipment in orbit.
