采用接枝共聚的方法将丙烯酸和苯乙烯聚合到单分散的Fe3O4纳米粒子上。然后通过静电自组装将苯胺分子键合到Fe3O4纳米粒子上，进一步聚合得到均匀的聚苯胺/Fe3O4(PANI/Fe3O4)纳米粒子(约35 nm)。最后，利用祖母绿聚苯胺与硝酸银的原位还原反应制备了单分散的Ag/PANI/Fe3O4纳米粒子。用傅里叶变换红外和紫外-可见光谱仪和透射电子显微镜对所得纳米颗粒的化学结构和形貌进行了表征。
Acrylic acid and styrene were polymerized onto monodispersed Fe3O4 nanoparticles using a grafting copolymerization method. Aniline molecules were then bonded onto the Fe3O4 nanoparticles by electrostatic self-assembly and further polymerized to obtain uniform polyaniline/Fe3O4 (PANI/Fe3O4) nanoparticles (approximately 35 nm). Finally, monodispersed Ag/PANI/Fe3O4 nanoparticles were prepared by an in situ reduction reaction between emeraldine PANI and silver nitrate. Fourier transform infrared and UV-visible spectrometers and a transmission electron microscope were used to characterize both the chemical structure and the morphology of the resulting nanoparticles.
