摘要

通过对Fe3O4纳米粒子接枝碳纳米管的单分散水溶液真空吸滤制备出一种新型的杂化碳纳米纸, 它与树脂浸润良好, 可以与复合材料一体成型。分别借助FE-SEM、EDS、BJH法和振动样品磁强计表征杂化碳纳米纸及其复合材料的微观形貌、元素组成、平均孔径分布和磁性能。在8.2~18 GHz频段内利用波导法测量碳纳米管共混复合材料和外贴杂化碳纳米纸/碳纳米管共混复合材料的电磁参数和吸波反射率。研究结果表明: 外贴一层杂化碳纳米纸(厚0.1 mm)后, 碳纳米管共混复合材料的磁损耗明显增加, 在8.2~18 GHz微波频段内吸波反射率基本上全部小于-10 dB(频宽大于9.7 GHz), 在15.42 GHz位置, 反射损耗峰达-43.18 dB, 远优于碳纳米管共混复合材料。

Abstract

A naval hybrid buckypaper was fabricated by vacuum filtration method with monodispersed solution of Fe3O4 decorated carbon nanotubes (CNTs), which was easy to be infiltrated by resin and can be co-cured with polymer composites. The morphology, element composition, pore size distribution, and magnetic of hybrid buckypaper were characterized by field-emission scanning electron microscope (FE-SEM), energy dispersive spectrometer (EDS), Barret-Joyner-Halenda (BJH) and vibrating sample magnetometer. The electromagnetic parameters of CNTs composite and hybrid buckypaper attached CNTs composite were investigated in the frequency range of 8.2-18 GHz with wave guide method and the reflection loss can be calculated. The hybrid buckypaper with only absorbing thickness of 0.1 mm attached CNTs composite possesses much broader absorbing bandwidth and larger reflectivity than those of CNTs composite, nearly all of which reflectivity is below -10 dB in frequency range of 8.2-18 GHz and the minimum value is -43.18 dB at 15.42 GHz.

Key words： Fe3O4/decorated CNTs; hybrid buckypaper; CNTs composite; electromagnetic parameter; reflection loss
