| 摘 要： | 对微乳液法制备纳米Al2(WO4)3进行了研究.分别以十六烷基三甲基溴化铵(CTAB)和二(2-乙基己基)磺基琥珀酸钠(AOT)为表面活性剂,在表面活性剂-正辛烷-盐水体系的W/O微乳液区成功地合成了纳米Al2(WO4)3.实验结果表明,以AOT为表面活性剂的微乳液体系制备的纳米Al2(WO4)3颗粒小,粒度分布均匀,其颗粒大小在40 nm左右且为球形.同时还在CTAB/正丁醇-正辛烷-盐水体系的W/O微乳液区、O/W微乳液区和液晶区合成了Al2(WO4)3,并将产物进行了比较.结果表明,在W/O微乳液区能够合成出粒度分布较均匀且粒径在100 nm以内的纳米Al2(WO4)3.

| Abstract: | The synthesis of Al 2(WO 4) 3 nanoparticles are studied by using microemulsion processing. Al 2(WO 4) 3 nanoparticles are synthesized successfully in W/O microemulsions of surfactant-n-octane-brine system, in which the surfactant is CTAB or AOT. The results indicate that Al 2(WO 4) 3 nanoparticles in AOT system are smaller about 40 nm in size and more uniform than that of CTAB system. As a comparison, Al 2(WO 4) 3 is also prepared in O/W microemulsion and liquid crystal regions of CTAB/n-butanol-n-octane-brine systems, respectively. The particles smaller than 100 nm in size should be got in W/O microemulsion. |
