ABSTRACT:
Provided is a magnetic graphite nanoplatelet, and a method of manufacturing nanocomposites by introducing the magnetic nanoplatelets into a composite matrix. Expanded crystalline graphite, in the form of graphite nanoplatelets, is mixed with magnetic particles to adhere the particles to the nanoplatelets. The magnetic graphite nanoplatelets are combined with a composite matrix, typically a polymer, to form a nanocomposite. In the presence of an applied magnetic field, the magnetic graphite nanoplatelets orient and align consistent with the magnetic field to yield a composite having enhance mechanical, electrical and thermal properties.
