Abstract
采用溶剂热法制备出一种包含BaTiO 3 和多壁碳纳米管(MWCNTs)的复合吸波剂. 通过透射电镜分析吸波剂的形貌发现: 粒径为15~30 nm的BaTiO 3 颗粒均匀地包覆在MWCNTs的外壁. 电磁波吸收性能分析表明: BaTiO 3 / MWCNT纳米复合吸波剂的反射损耗(RL)要大于BaTiO 3 和MWCNTs, 这是由于其有更好的阻抗匹配和更高的复合磁导率. 当单层材料的计算厚度为2mm时, BaTiO 3 /MWCNT纳米复合吸波剂的RL在9.6~13.1 GHz的频段中超过了–10dB, 同时在10.4 GHz处达到最大值–37.5 dB. 为了研究BaTiO 3 /MWCNT纳米复合吸波剂与聚丙烯腈(PAN)基体的相容性和其杂化纤维的可纺性, 采用静电纺丝成型制备吸波剂含量为10wt%的PAN杂化纤维. 通过X射线衍射和扫描电子显微镜分析发现: BaTiO 3 /MWCNT纳米复合吸波剂成功与PAN纤维杂化, 吸波剂的结构在成型过程中没有变化, 吸波剂的添加并未影响纤维形貌.
