Graphite Nanoplatelets as Reinforcements for Polymers: The Effect of Nanoreinforcement Adhesion on Structural and Electrical Properties

摘要

A new nanoplatelet graphite material was developed by exfoliation of graphite. An appropriate surface treatment was established for the new material, which produced a nanographite platelet reinforcement that increased the mechanical properties of an epoxy system better than some commercially available carbon materials at the same volume percentage. In addition, the exfoliated graphite material has been shown to percolate at only 3 volume percent. Measurement of the impedance of this material indicates that it could be used to produce polymer matrix composites for new applications such as electrostatic dissipation and EMI shielding.
