摘要

本研究制备了含有MnZn铁氧体/聚苯胺(Pani)涂层的多壁碳纳米管(PCNTs)的雷达吸收结构(RAS)，观察其在x波段的微波吸收行为。采用溶胶-凝胶自燃烧法制备了铁氧体纳米颗粒。采用x射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、热重分析(TGA)和振动样品磁强计(VSM)对制备的纳米铁氧体粉末进行了表征。制备了纳米铁氧体粒子和不同浓度PCNTs填充的RAS，利用矢量网络分析仪(VNA)研究了它们的微波吸收行为，并估计了后期反射损耗(RL)。对于铁氧体固定样品，估计双层RAS的最小RL损耗在10.8 GHz时为- 29.06 dB，对于PCNT固定样品，在9.6 GHz时为- 33.07 dB。进一步，研究了它们的力学行为。

Double-layered radar absorbing structures of MnZn ferrite/Pani-coated MWCNT filled nanocomposites for X-band frequencies

ABSTRACT In this study, radar absorbing structures (RAS) containing MnZn ferrite/Polyaniline (Pani) coated multi-walled carbon nanotubes (PCNTs) were fabricated to observe their microwave absorption behaviour in X-band frequency range. The ferrite nano particles were prepared by sol–gel auto combustion method. The prepared nano ferrite powder was characterised using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and vibrating sample magnetometer (VSM). RAS filled with nano ferrite particles and PCNTs in different concentrations were fabricated to investigate their microwave absorption behaviour using a vector network analyzer (VNA) and later reflection loss (RL) is estimated. The minimum RL loss estimated for double-layered RAS are found to be −29.06 dB at 10.8 GHz for ferrite fixed samples and −33.07 dB at 9.6 GHz for PCNT fixed samples. Further, their mechanical behaviour is examined.

期刊介绍： Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably.
