摘要： A method for preparing expanded foamed graphite film includes the following steps: Step A: impregnating a synthetic graphite film into an intercalator for an interlayer intercalation treatment to prepare an intercalated graphite film; Step B: performing a thickness-limited expansion and foaming to the intercalated graphite film obtained in Step A, with an expansion ratio y of 2-25, to obtain an expanded foamed intercalated graphite film.
