The nanocomposite multilayer film (NCMF) of substituted BaFe12O19 and TiO2 was prepared using sol-gel method. BaFe10.5Al1.5O19,BaFe10.1Al1.9O19 and BaFe11.4Cr0.6O19 with different absorption frequencies were selected to fabricate the multilayer film with TiO2. The morphology, crystalline structure and microwave absorption property of the NCMF were investigated with an atomic force micros- copy, X-ray diffraction and vector network analyses.The results show that the NCMF is uniform without microcracks and it is an ideal microwave attenuation material with a broad frequency range. Its maximum loss efficiency is about –40 dB. The frequency range with the loss above –10 dB is more than 7 GHz. The multilayer film assembles the achievements of each layer film. Moreover, the compounding of ferrites with TiO2 is helpful to absorb more microwave energy. TiO2particles block the growth of ferrite grains and make most of their size within nanometers. TiO2also improves the dielectric loss efficiency of the NCMF. |
| 用溶膠——凝膠方法制備BaFe12O19和TiO2替代的納米復合材料高分子多層膜(NCMF)。選擇具有不同吸收頻率的BaFe10.5Al1.5O19, BaFe10.1Al1.9O19 和BaFe11.4Cr0.6O19與TiO2制備多層膜。用顯微鏡、X-射線衍射、矢量網(wǎng)絡分析研究NCMF的形態(tài)特點、晶體結構和微波吸收性能。結果表明,NCMF均勻一致沒有微裂隙,它是一種理想的具有寬范圍的頻率的微波衰減材料,其最高損失頻率大約為–40 dB。損失率為–7 dB以上的頻率范圍高于7 GHz。多層膜聚集了每一層膜的優(yōu)勢特點。此外,陶鐵磁體與TiO2形成的復合物能夠幫助吸收更多的微波能量。TiO2顆粒能夠阻止陶鐵磁體顆粒的生長,并使控制其顆粒大小位于納米范圍內(nèi)。TiO2能夠降低NCMF的介電損耗效率。 |
