摘要: Abstract Graphitic particles showing polyhedral structures of 100–800 nm diameter (average 327 nm) were fabricated by laser vaporization graphite in a high pressure N 2 gas environment (0.9 MPa). From X-ray photoelectron spectroscopy, three atomic percent (at.%) the nitrogen atoms was detected (PG) particles. Nonuniformity distribution indicates bonding formation at defects or domain boundaries polyhedra forming PG Adding improve tribological properties polyimide-based composite. In particular, provided better wear-resistance than those and related nanocarbon materials.
