US Patent 8075794 - Magnetic graphite nanoplatelets


This patent from Teledyne Scientific and Imaging teaches a magnetic nanomaterial based on graphite in which the thermal conductivity can be adjusted in a particular direction or plane by controlling the orientation of the magnetic graphitic material. Claim 1 reads: 

1. A magnetic graphite nanoplatelet compound, comprising:

a plurality of expanded graphite nanoplatelets having a random orientation; and

magnetic metal particles dispersed among, and adhered to, the plurality of graphite nanoplatelets.
