摘要
用共沉淀法制备磁流体的磁核一纳米Fe3O4,液体石蜡作基液和混合表面活性剂作分散介质而成功地制备出满足制备磁性药物微球需要的油基磁流体。研究了纳米Fe3O4、液体石蜡用量,表面活性剂的种类和组成比以及不同温度对磁流体性质的影响。并用XRD、TEM、旋转粘度计、磁天平等对磁流体的物相、粘度、磁性以及稳定性等进行了表征。
The nucleus of magnetic fluids nano-Fe3O4 was prepared by chemical coprecipitation. It was prepared triumphantly that the oil-based magnetic fluids with olefin as basal and mix surfactant as dispersant, while is suffice must needs for preparation of magnetic drug micro-sphere. Where have investigated that the quantity of nano-Fe3O4, olefin; infection of species and ratio of surfactant as well as temperature on properties of magnetic fluids. The properties of magnetic fluids have'been characteristic by XRD, TEM、 rotational viscometer and magnetic scale, including magnetism, viscosity and stability.
