Abstract

MWCNT/Fe3O4/Si3N4 composite was synthesized via hydrothermal synthesis. The morphology and structure of MWCNT/Fe3O4/Si3N4 were investigated by means of SEM, XPS, XRD, and FT-IR. Their electromagnetic parameters were measured by a vector network analyzer. The microwave attenuation properties of as-synthesized composite could be modulated by regulating the feed ratio of MWCNT, Fe3O4, and Si3N4. According to the different amounts of modified nano Fe3O4 added, they are labelled as S1-S3. When the feed ratio is 3:15:20, the maximum reflection loss value of the sample is −23.3 dB at 14.4 GHz, the corresponding thickness is 2.5 mm, and the corresponding effective absorption bandwidth is 5.36 GHz. Moreover, the test results of the thermogravimetric analyzer show that the composite material has excellent heat resistance. Our research results provide a reference value for the development of excellent heat resistance and high-performance MWCNT-based microwave absorption composite materials.

MWCNT/ fe3o4 / si3n4三元复合材料的制备及其微波吸收性能

采用水热法合成了MWCNT/Fe3O4/Si3N4复合材料。采用SEM、XPS、XRD、FT-IR等手段研究了MWCNT/Fe3O4/Si3N4的形貌和结构。用矢量网络分析仪测量了它们的电磁参数。通过调节MWCNT、Fe3O4和Si3N4的进料比，可以调节复合材料的微波衰减特性。根据改性纳米Fe3O4添加量的不同，将其标记为S1-S3。当进给比为3:15:20时，样品在14.4 GHz处的最大反射损耗值为−23.3 dB，对应的厚度为2.5 mm，对应的有效吸收带宽为5.36 GHz。热重分析仪的测试结果表明，复合材料具有优良的耐热性。研究结果为开发耐热性能优异、性能优良的mwcnts基微波吸收复合材料提供了参考价值。
