摘要:
为了获得高性能复合气凝胶吸波材料,以螺旋碳纳米管(Helical carbon nanotubes,HCNTs)和聚苯胺(Polyaniline,PANI)为吸波剂,聚乙烯醇(Polyvinyl alcohol,PVA)为基体,采用定向冷冻法和低温原位聚合法制备了高性能螺旋碳纳米管聚苯胺/聚乙烯醇复合气凝胶(HCNTsPANI/PVA composite aerogels,HPPA)。采用扫描电子显微镜、红外光谱仪、拉曼光谱仪和X射线衍射仪对HPPA复合气凝胶的形貌与结构进行表征,并使用矢量网络分析仪测定HPPA复合气凝胶的电磁参数和吸波特性。结果表明:所制备的HPPA复合气凝胶具有优异的吸波性能,最小的反射损耗为-69.08 dB,有效吸收带宽为4.20 GHz;HPPA复合气凝胶优异的吸波性能主要归因于其定向的多孔结构和非均匀介质界面形成的良好阻抗匹配特性和多重极化协同效应。该文为构建高性能复合气凝胶吸波体系提供了新思路。
