To popularize scientific achievements in construction the main results of Russian and foreign scientists’ research are published in the form of abstract. Within the investigation «Development of polymer composite materials based on epoxy binder and functionalized carbon nanotubes (f-CNT)» radio-absorbing materials based on epoxy binder and f-CNT have been created. These materials possess the similar absorbing and reflecting characteristics but their thicknesses are 25—30 times less than those of composites based on microsize carbon fillers (technical carbon and graphite) and 1,5—2,0 times less in respect to the composites based on native CNT. Such composites with the same thicknesses and weakening factor are characterized with reflection factor which is 4,5—5,5 times less than that of composites based on microsize carbon fillers and 1,1—1,4 times less in respect to the composites based on native CNT. Within the range «Production and properties of metal-containing nanoparticles (Fe, Co, Ni, Zn, Ce, Cd, Pd, Ag, Mo) stabilized by detonation synthesis nanodiamond and high pressure polyethylene» composite nanodimensional materials were obtained. These materials have great application potentialities to solve the problems of electromagnetic compatibility and in particular to create multi-layer radio wave absorbing materials and coatings possessing high efficiency, that was shown in the work. Composite nanomaterials can be used as the model systems to study their interaction with electromagnetic emission and to create metamaterials based on these com posite nanomaterials with the use of distinctive feature of physical properties of nanosize substance. Specialists can use published materials in their scientific and practical activities.
