Preparing graphite nanosheets by sonicating expanded graphite

摘要

Natural graphite flakes were treated by intercalating, water-washing, drying and expanding, forming expanded graphite. Graphite nanosheets were prepared by sonicating expanded graphite in a liquid medium. The corresponding products were characterized by scanning electron microscope. The results show that the graphite nanosheets as-prepared have an average diameter of 16μm and an average of thickness of 25 nm.
