Creation and research of antistatic carbon coatings on fabric 05С8-КВ, modified by metal clusters

Abstract

Application modes have been developed and carbon coatings modified with metal clusters on 05S8-KV fabric (manufacturer OJSC Mogotex) were created. The surface morphology of this coated fabric was investigated. It was shown that during the deposition of coatings from 12X18H10T steel targets a droplet phase is present on the coatings (the maximum droplet size reaches 3.5 μm). The paramagnetic absorption of the system carbon coating – clusters from the 12X18H10T steel target is investigated. It was found that the EPR spectrum contains a spectral line 94.4 mt wide, which indicates a high concentration of magnetic resonance centers, the effective value of the g-factor is 2.26 ± 0.01. In addition, a narrow spectral line with an effective g-factor of 2.04 ± 0.01 is recorded in the spectrum, the linewidth is 4.3 mt, which is associated with a high local concentration of unpaired electrons in carbon clusters with a weak nonresonant absorption at UHF (ultra-high frequrncy). The result of measuring the specific surface resistance on fabrics with this coating (side 1 / side 2) is 2.3.109 and 4.8.109 ohms, respectively, which is slightly lower than for a pure carbon coating.
