摘要(Abstract)：

通过溶胶凝胶法制备了尖晶石型锂锌铁氧体(Li0.35Zn0.3Fe2.35O4),并采用界面聚合法制备了不同质子酸掺杂的锂锌铁氧体/聚苯胺(Li0.35Zn0.3Fe2.35O4/PANI)树枝状复合吸波材料。通过傅里叶变换红外光谱(FT-IR)、X射线衍射法(XRD)、扫描电子显微镜(SEM)和矢量网络分析(VNA)等现代分析技术对其化学组成、微观形貌、电磁性能、吸波性能进行了表征。结果表明:PANI纤维在Li0.35Zn0.3Fe2.35O4表面按树枝状生长机制进行接枝聚合。以盐酸(HCl)掺杂制备的Li0.35Zn0.3Fe2.35O4/PANI树枝状复合吸波材料中PANI纤维长径比最大(直径为75~90 nm,长度为710~800 nm),反射损耗小于?10 d B的频宽可达到4.1 GHz,分别在频率为3.9和15.8 GHz时,其反射损耗峰值分别为?20.5和?33.1 d B,具有良好的吸波性能。
