摘要

磁流变液是一种发展迅速具有优异性能的新兴智能材料, 具有快速的响应时间、可逆的流变特性、可控的机械性能和广泛的操作温度, 被广泛地应用于减震器、离合器、传感器、阻尼器等工程领域。本研究采用一步水热法制备出中空结构Fe3O4磁性纳米球, 然后采用扫描电子显微镜、透射电子显微镜、X-射线衍射和超导量子磁力干涉仪等分析技术对其形貌、结构和磁性能等综合特性进行了深入研究, 进而利用制备的中空Fe3O4磁性纳米球为分散相制备出均匀的磁流变液, 最后采用旋转流变仪和直接观察法分别测试了磁流变液的流变性能和沉降稳定性。

Abstract

Magnetorheological fluid (MRF) is a rapidly developing emerging intelligent material with excellent properties, featuring fast response time, reversible rheological properties, controllable mechanical properties and a wide range of operating temperature. It is widely used in engineering fields such as shock absorbers, clutches, sensors and dampers. In this paper, hollow structured Fe3O4 magnetic nanospheres were synthesized by using a facile one-step hydrothermal method, and then their comprehensive properties such as morphology, structure and magnetic properties were thoroughly characterized by using analytical techniques such as scanning electron microscope, transmission electron microscope, X-ray diffraction and superconducting quantum magnetic interferometry, and then, a homogeneous magnetorheological fluid was prepared by using the prepared hollow Fe3O4 magnetic nanospheres as the dispersed phase, and finally the rheological properties and sedimentary stability of magnetorheological fluid were tested by rotational rheometer and direct observation method respectively.
