A method for providing intercalated graphite flake with improved exfoliation characteristics, specifically, improved expansion pressure, is presented. The method includes treating graphite flakes with an oxidizing intercalant solution to provide intercalated graphite flakes; washing the intercalated graphite flakes; and adding a surfactant to the washed graphite flakes. The invention also includes the intercalated graphite flakes thusly prepared. |
