通过超声辅助水热法（UAHM）实现了磁性纳米粒子对碳纳米管表面的修饰。测定了超声处理时间对磁性碳纳米管复合材料晶体结构、磁性能和化学成分的影响。使用 X 射线衍射 (XRD)、傅里叶变换红外光谱 (FTIR)、透射电子显微镜 (TEM) 和振动样品磁力测定来表征复合材料的物理、化学和磁性能。通过 UAHM 合成的复合材料表现出超顺磁性。超声处理时间是影响复合材料结构和磁性能的关键因素。通过简单地控制超声处理时间，可以选择性地调节Fe氧化物的晶相结构，并可以有效地调节MC的磁性能。
The decoration of CNTs surface by magnetic nanoparticles was achieved by an ultrasonication-assisted hydrothermal method (UAHM). The effect of ultrasonication time on the crystal structure, magnetic performance, and chemical composition of the magnetic CNT composite material was determined. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and vibrating sample magnetometry were used to characterize the physical, chemical, and magnetic properties of the composites. The composites synthesized via the UAHM exhibited superparamagnetic properties. The ultrasonication time was a critical factor that affected the structure and magnetic performance of the composites. By simply controlling the ultrasonication time, the crystal phase structure of Fe oxide could be selectively modulated and the magnetic performance of the MCs could be effectively tuned.
