摘要
采用沸腾回流法制备了Ni0.4Zn0.35Co0.25LaxFe2-xO4/碳纳米管(CNTs)复合吸波材料,考察了镧(La)的掺杂量对复合材料磁性及吸波性能的影响。研究表明:沸腾回流法制备的铁氧体为单相尖晶石结构,纳米铁氧体粒子成功包覆在碳纳米管上。La3+掺杂量x=0.07时,产物的矫顽力(Hc)最大,且吸波性能最佳。
Ni0.4Zn0.35C0.25LaxFe2-xO4/CNTs wave-absorbing composites were prepared by refluxing method. The effects of doping La3＋ on magnetic and wave-absorbing properties was studied. The research indicated that Ni0. 4 Zn0. 3~ Coo. 25 Fe20~ ferrites prepared had a single phase spinal structure and had been successfully coated by nanoferrites. As x= 0. 07, samples had the maximal optimum coercivity and absorption value.
