| 本文采用沉淀法和溶胶-凝胶法分别制备了NiFe2O4和TiO2,采用XRD和SEM对两种粒子进行了表征,结果表明成功制备了粒径大小较为均匀的目标产物。我们采用CTAB对NiFe2O4进行了改性,通过IR和ZETA电位测试的结果,表明对NiFe2O4已经成功的进行了有机改性。以改性NiFe2O4和TiO2 作为稳定粒子采用两步法制备了W/O/W型多重Pickering乳液,采用数码照片和光学显微照片观察所制备的乳液的宏观与微观形貌。研究表明,制备的单重Pickering乳液粒径较为均匀,多重Pickering乳液粒径范围稍宽,但二者稳定性能都非常良好。 |
| 英文摘要: |
| STiO2 and NiFe2O4 were prepared by precipitation method and sol-gel method, and the SEM and XRD had been used to characterize that the uniform particle size of NiFe2O4 and TiO2 had been successfully achieved. Then, the results of IR and Zeta potential tests showed that the NiFe2O4 was successfully modified by CTAB. Two-step process was adopted to prepare the W/O/W multiple Pickering emulsion by the stability of modified NiFe2O4 and TiO2, and the macro and micro morphology of the prepared Pickering emulsion had been observed by digital photo and optical microscope. In this study, the size of single Pickering emulsion was uniform, and the size of multiple Pickering emulsion was wider, but the two Pickering emulsion all had very good stability. |
