摘要

为了充分发挥Fe₃O₄磁性纳米材料在电磁领域的应用,通过水热法结合溶胶-凝胶法,制备出核壳结构Fe₃O₄@ZnO纳米微粒,再将其涂覆在织物上研究其电磁屏蔽性能。采用扫描电子显微镜、透射电子显微镜、X射线衍射仪、X射线能谱仪以及傅里叶红外光谱仪对Fe₃O₄@ZnO纳米微粒进行表征;采用振动样品强磁计分析其磁性能;采用织物防电磁辐射性能测试仪分析复合织物的电磁屏蔽性能。结果表明:获得的产物是以Fe₃O₄为核、以ZnO为壳的核壳结构纳米微粒,主体粒径约为450nm,壳层厚度约为25nm;Fe₃O₄@ZnO纳米微粒具有良好的磁性;Fe₃O₄@ZnO复合织物在低频范围内屏蔽效能最高可达50.91dB,具有较好的电磁屏蔽性能。

Abstract

In order to promote the application of Fe₃O₄ magnetic nanomaterials in electromagnetic field,Fe₃O₄@ZnO with core-shell structure nanoparticles were prepared by hydrothermal method combined with sol-gel method,and then coated on fabric for studying its electromagnetic shielding property.The Fe₃O₄@ZnO nanoparticles were characterized by scanning electron microscope,transmission electron microscope,X-ray diffractometer,X-ray energy spectrometer and fourier infrared spectrometer.The magnetic property was analyzed by vibration sample magnetometer.The electromagnetic shielding property of the fabric was tested by the electromagnetic shielding property tester.The results indicated that the product was core-shell nanoparticles with Fe₃O₄ as the core and ZnO as the shell.The particle was about 450nm in diameter and the shell thickness was about 25nm.The Fe₃O₄@ZnO nanoparticles had good magnetic property.The Fe₃O₄@ZnO had a shielding effectiveness of 50.91dB in low frequency range.Therefore,it had good electromagnetic shielding property.
