Application of nanocarbon structures to optimize the design parameters of conductive surfaces of electroadhesive pads

This paper presents a measurement experiment that investigates the effect of using nanocarbon structures coating conducting surfaces energized with high voltage on the conditions for generating high-voltage phenomena. The phenomena studied included current leakage of an insulated plate, ionization phenomena of gases surrounding the plate, optical phenomena accompanying ionization, and detection of gases synthesized under high voltage. The tests were conducted in a gaseous environment with proportions matching the composition of air at normal conditions and at reduced pressure. For comparison, the series of tests was repeated for conductive metallic wafers without the addition of nanostructures. The aim of the study was to analyze the application of nanocarbon structures for the construction of more efficient electroadhesive pads with lower power losses related to current leakage, electroadhesive pads with higher generated electrostatic force and a wider range of applicability for the attraction of different materials. The application of the nanocarbon structure on the electroadhesive pad resulted in the generation of corona discharges in the form of electric arcs and a violet-pink glow.
