CNT/结晶铁纳米复合材料（见图）具有优异的微波吸收特性。这种吸收特性被证明是由于碳纳米壳中晶体 Fe 的限制而产生的，主要源于磁效应而不是电效应——复介电常数和磁导率取决于 CNT/Fe 纳米胶囊的形状和相。
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.
