CNT/crystalline Fe nanocomposites (see Figure) have excellent microwave-absorption characteristics. This absorption property is shown to result from the confinement of crystalline Fe in carbon nanoshells, deriving mainly from magnetic rather than electric effects—the complex permittivity and permeability depend both on the shape and phase of the CNT/Fe nanocapsulates.
