摘要
利用化学气相沉积（CVD）技术,在外加磁场（0.6T）和零磁场下,以二茂铁为原料,在高温下裂解获得铁/碳复合材料,在外加磁场（0.6T）下热解获得的铁/碳复合材料具有管状形貌,外径为50-60nm,内径为30-40nm,管状铁/碳复合吸波材料在2-18GHz的范围内,吸收峰的位置在25GHz之间,最大吸收为18dB,随着材料厚度的增加,吸收峰向低频移动.
Taken chemical vapor deposition method and ferrocene as the raw material, preparedMWNTs∕Fe composite material under magnetic field （0.6T） and no magnetic field. Under magnetic field（0.6T）, the composite had tubular shape with an outer diameter of 50-60nm and inner diameter of 30-40nm. The absorption peak of MWNTs∕Fe was between 2 -5GHz in the range of 2 -18GHz, withmaximum absorption of 18dB,increased wiph the thickness of the composite material, the absorptionpeak moved toward low frequency.
