- 将硅烷化处理的 Fe 3 O 4 纳米颗粒与聚二甲基硅氧烷（ PDMS ）混合得到可用于直写式 3D 打印的复合材料墨水，并利用直写式 3D 打印机完成复杂结构的制备。该铁氧体复合材料的饱和磁化强度为 37 emu/g ，剩余磁化强度为 0.5 emu/g ，矫顽力为 16 oe ，有效磁导率的工作频率范围可达 5 GHz ，在复杂结构磁体的制造以及射频电路电子器件应用方面表现出良好的前景。
- Abstract:
- ： The silanized Fe 3 O 4 nanoparticles were mixed with polydimethylsiloxane （ PDMS ） to obtain a composite material ink that could be used for direct writing 3D printing ， and a direct writing 3D printer was used to complete the preparation of complex structures. The ferrite composite material had a saturation magnetization of 37 emu/g ， a residual magnetization of 0.5 emu/g ， a coercivity of 16 oe ， and an effective magnetic permeability operating frequency range of up to 5 GHz. The composite material shows good prospects in the manufacture of complex structure magnets and the application of radio frequency circuit electronic devices.
