Název v původním jazyce
Development of conductive composite coatings with specific functional properties
Popis výsledku v původním jazyce
The article presents the development results of advanced composite coatings with enhanced electric conductivity intended for detection of disruptions in the base material structure. Conductive coatings were prepared from a low viscosity epoxy resin and three types of admixtures - amorphous carbon black, micronized graphite and multi-walled carbon nanotubes (MWCNTs). Such multicomponent coatings were tested together with hand-applied graphite layers and commercial spray-applied colloidal graphite and copper-based electroconductive coatings, for comparison. The influence of the admixtures on electrical conductivity was evaluated. The course of impedance response of polymer coatings, graphite layers and copper layers was investigated during bending in press, drilling and high-speed loading by rifle projectiles. Conductive coatings showed a distinctive change in impedance under mechanical damaging by drilling and during dynamic testing. These functional coatings represent innovative direction for the development of new progressive ballistic and anti-blast shield systems.
