Continuous process for producing exfoliated nano-graphite platelets

摘要

Graphite nanoplatelets of expanded graphite and composites and products produced therefrom are described. The graphite is expanded by microwaves or radiofrequency waves in the presence of a gaseous atmosphere. Various devices are described for expanding the intercalated graphite by means of microwaves or other radiofrequency waves to produce the expanded graphite. These devices can be used in a continuous process.
