Abstract
Intercalated graphite flake which has enhanced exfoliation volume characteristics at relatively low exfoliation temperatures, e.g., 600° C. and even lower, is made by adding an organic expansion aid to the intercalant solution and heating a blend of intercalated particles and an organic reducing agent in the temperature range of 25° to 125° C.
