标题
Synthesis and characterization of monodisperse magnetic composite
particles for magnetorheological fluid materials

Abstract
Monodisperse magnetic composite particles (MCP) were prepared and characterized for a study of magnetic field-responsive fluids.
Magnetic composite particles used are iron oxide-coated polymer composite particles, which were synthesized through in situ coating of
iron oxide onto pre-existing polymer particles by the reduction of ferrous fluids. For a uniform and bulk coating of iron oxide, the porous
structure was introduced into the substrate polymer particles through a two-step seeded polymerization method. Moreover, surface cyano-
functionality was born from acrylonitrile unit of substrate polymer and it played an important role in obtaining successful uniform coating.
The structure of the composite particle was analyzed by using a thermo gravimetric analysis (TGA) and a X-ray diffraction (XRD) analysis.
The magnetization property of the particle was also observed. Then, the rheological properties of monodisperse magnetorheological (MR)
suspensions of magnetic composite particles were examined under a magnetic field using a parallel-plate type commercial rheometer. From
therheologicalmeasurements,itwasfoundthatMRpropertiesofthemagneticcompositesuspensionsaredependentontheironoxidecontent
and the fluid composition.

用于磁流变液材料的单分散磁性复合材料颗粒的合成和表征
摘要
制备、表征了单分散磁性复合粒子(MCP), 并用于磁场感应液的研究。使用的磁性复合粒子是氧化铁涂层的聚合物复合粒子,通过亚铁液体在聚合物颗粒经原位还原形成氧化铁涂层。为了得到均匀、大面积的氧化铁涂层,多孔结构通过两步种子聚合法引入到基体聚合物颗粒中。此外,表面腈基官能团由基体聚合物的丙烯腈单体导入,对于得到均匀涂层起到重要的作用。利用热重分析法(TGA)和X射线衍射(XRD)分析了复合粒子的结构。
观察到粒子带有磁化特性。然后,磁性复合粒子形成的单分散磁流变(MR)悬浮液的流变特征在磁场中用购买的平行板式流变仪测定。通过流变学测量发现磁性复合悬浮液磁流变特性取决于氧化铁的含量和流体组分。
离成功还差一点
