放射状ZnO-Fe3O4的制备及其微波吸收1

Synthesis and microwave absorption properties of actinomorphic tubular ZnO-Fe3O4 nanocomposites

中文摘要英文摘要

采用两步液相合成法制备出放射状ZnO-Fe3O4复合纳米管束.ZnO 纳米管束的管壁厚度大约为60nm,管的直径约为350 nm,小于40nm的Fe3O4纳米颗粒连续包覆在ZnO纳米管束的表面.分别以Fe3O4纳米颗粒、ZnO-Fe3O4复合纳米管束及放射状ZnO纳米管束作为吸收剂、酚醛树脂为粘接剂研究了它们的微波吸收性能,结果表明ZnO-Fe3O4纳米复合材料的微波吸收性能优于纯相Fe3O4纳米颗粒和放射状ZnO, 并且随着ZnO在ZnO-Fe3O4纳米复合材料中含量的提高,微波吸收性能逐渐增强,直到ZnO的含量达到60%时微波吸收效果最佳,复合材料的微波吸收达到14.3 dB。另外,复合材料中含量不同其吸收频带不同。结果表明,这种复合材料可作为频带可调的良好微波吸收剂。

he synthesis of actinomorphic tubular ZnO-Fe3O4 nanocomposites was by a two-step chemical solution method. the wall thicknesses of the ZnO nanotubes are all about 60 nm,inner diameters of the tubes are all about 350 nm, ZnO nanotubes have been coated with Fe3O4 nanoparticles, and the sizes of Fe3O4 nanoparticles are below 40 nm. Compared with that of pure ZnO nanotubes and Fe3O4 nanoparticles, enhanced microwave wave absorption of actinomorphic tubular ZnO-Fe3O4 nanocomposites was observed, and the microwave wave absorption performance of ZnO-Fe3O4 nanocomposites increases with the increase of the content of ZnO in ZnO-Fe3O4 nanocomposites. When the content of ZnO is 60%,the maximum reflection loss is 14.3dB.The results indicate that the composites are of excellence with respect to microwave absorption.
