dc.description.abstract1. The technology of fabrication of a metal-textile material for shielding electromagnetic fields was developed. It is based on the influence of a constant magnetic field of high heterogeneity from two magnetic conductors on a textile material impregnated with a magnetic fluid containing ferromagnetic nanoparticles. This has made it possible to reduce magnetic fluid consumption from 45‒50 g/m2 to 35 g/m2 compared to its counterparts and increase the number of shielding particles implanted into fabric fibers from 1.5‒1.6 g/m2 to 2.9‒3.0 g/m2. 2. The technology of manufacturing metal-polymeric material has been developed. It differs from its counterparts in pre-treatment of a mixture of iron ore concentrate and liquid polymer by ultrasonic radiation at a frequency of 23 kHz and amplitude of 45–50 μm. This has enabled an increase in the dispersity of the iron ore substance by mechanical action and ensured uniform distribution of particles in the polymer by intensive ultrasonic mixing. 3. The study of protective properties of a single-layer textile material has shown that the guaranteed shielding factor in protection against the magnetic component of the electromagnetic field of industrial frequency and its harmonics amounted to 6. The shielding factor of the electrical component was 1.5. The shielding factor in protection against an electromagnetic field of ultrahigh-frequency (2.45 GHz) was 3.6. Such values indicate the suitability of the studied materials for the manufacture of personal protective means. 4. Studies of protective properties of the metal-polymer material have shown that the guaranteed shielding factor for the magnetic component of the electromagnetic field of industrial frequency and its harmonics is 3. The shielding factor for the electrical component is 2. The shielding factor for the electromagnetic field of ultra-high frequency (2.45 GHz) is 5.7. Such protective properties indicate the possibility of using the material as a means of collective protection, for example in facing surfaces of large areas.uk_UA
