摘　　要：以硫酸亚铁、苯酚和六次甲基四胺为原料,采用水热法制备出酚醛树脂(PFR)包覆的Fe3O4(Fe3O4@PFR)纳米粒子,分散于离子水中,得水基Fe3O4@PFR磁性纳米流体,经过X-射线衍射仪(XRD)、傅里叶红外光谱仪(FTIR)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)和振动磁强计(VSM)进行表征。结果表明,Fe3O4纳米晶体的平均粒径为20 nm,在室温下表现为超顺磁性,Fe3O4@PFR磁性纳米流体具有很好的稳定性和生物相容性。Ferrous sulfate, phenol and hexamethylene tetramine as raw materials. Using hydrothermal syn- thesis of phenolic resin coated Fe3O4 （ Fe3O4 @ PFR） nanoparticles, dispersing in deionized water, Fe3O4 @ PFR magentic nanofluid was obtained. The products are characterized by XRD, FTIR, SEM, TEM and VSM instruments. The results showed that Fe3O4 nanocrystals around 20 nm size possess excellent super- paramagnetic properties at room temperature. Fe3O4@ PFR magnetic nanofluids possess outstanding stabil- ity with good biological compatibility.
