Patent ID: 7824771

Claim:
A carbon-metal composite material prepared by performing a heat treatment on a powder including a coordination polymer, wherein the carbon-metal composite has a sheet resistance of 8 mΩ/sq or less under a pressure of 100 kg f /cm 2 , and wherein the coordination polymer is a compound of formula (1): M x L y S z (1) where M is a metal selected from the group consisting of transition metals, group 13 , group 14 , group 15 , lanthanides, actinides, and combinations thereof; L is a multi-dentate ligand simultaneously forming an ionic bond or a covalent bond with at least two metal ions; S is a monodentate ligand forming an ionic bond or a covalent bond with one metal ion; and the number of functional groups of L that can bind to the metal (M) ion is d, and x, y, and z are integers satisfying yd+z≦6x, x≧1, y≧1, and y+z≧1.
