摘要：

Graphite nanoplatelets (GNPs) were reacted with transition metal (M) carbonyls followed by annealing and compaction to remove the CO ligands and form bis-hexahapto bonds between the GNP surfaces. The M-GNP films (M = Cr, W, Mo) were characterized with Raman spectroscopy and conductivity measurements. It was observed that interconnection of the graphitic faces of GNPs by bis-hexahapto metal coordination resulted in a decrease of electrical conductivity. The complexes offer promise as catalysts and in the fabrication of new 3-D electronic materials. (C) 2012 Elsevier B.V. All rights reserved.
