Abstract

To meet the comprehensive demand for flexible microwave absorbing (MA) materials, a novel MA rubber containing homemade Polypyrrole nanotube (PPyNT) is produced based on the natural rubber (NR) and acrylonitrile-butadiene rubber (NBR) blends. To achieve the optimal MA performance in the X band, the PPyNT content and NR/NBR blend ratio are adjusted in detail. The 6 phr PPyNT filled NR/NBR (90/10) composite has the superior MA performance with the minimum reflection loss value of -56.67 dB and the corresponding effective bandwidth of 3.7 GHz at a thickness of 2.9 mm, which has the merits in virtue of achieving strong absorption and wide effective absorption band with low filler content and thickness compared to most reported microwave absorbing rubber materials over the same frequency. This work provides new insight into the development of flexible microwave-absorbing materials.

摘要

为满足对柔性微波吸收（MA）材料的综合需求，基于天然橡胶（NR）和丁腈橡胶（NBR）共混物制备了一种含有自制聚吡咯纳米管（PPyNT）的新型MA橡胶。为在X波段实现最佳MA性能，详细调整了PPyNT含量和NR/NBR共混比。填充6份PPyNT的NR/NBR（90/10）复合材料具有优异的MA性能，在厚度为2.9 mm时，最小反射损耗值为-56.67 dB，相应的有效带宽为3.7 GHz，与大多数报道的同频率微波吸收橡胶材料相比，具有在低填料含量和厚度下实现强吸收和宽有效吸收带的优点。这项工作为柔性微波吸收材料的开发提供了新的见解。
