Aspects of Coatings on Buckypaper as a Study into the Expected Effects of Coatings on Carbon Nanotube Wires

Buckypaper (BP) was used as an accumulation of nanotubes to simulate carbon nanotube (CNT) wires study the interaction between four different insulating coating materials and CNTs. The wettability electrical conductivity performance each CNT/coating pair assessed. BP prepared by filtering a sonicated solution single-walled N,N-Dimethylformamide, through polytetrafluoroethylene (PTFE) membrane 0.45 µm pore size. It observed with Scanning Electron Microscopy, its chemical composition determined X-ray Photoelectron Spectroscopy, imperfections purity measured Raman Spectroscopy porosity (%) distribution obtained Nitrogen Physisorption. results showed similar surface structure that reported CNT wires. free energy Owens-Wendt method, tension coatings calculated pendant drop measurements find adhesion parameters. Epoxy resin highest adhesion, which resulted in infiltration into decreased 65%. In contrast, varnish much lower level lowest decrease (9.3%).
