| 摘要: |
| 以脂肪醇聚氧乙烯醚(AEO-3)、氯化亚砜和N,N,N',N'-四甲基-1,4-丁二胺为原料,通过两步法合成一种Gemini阳离子季铵盐型表面活性剂(氯化N,N,N',N'-四甲基-N,N'-双十二烷基聚氧乙烯醚-1,4-丁二铵盐)。通过傅里叶变换红外光谱FTIR和核磁共振氢谱H1NMR对其结构进行表征。利用合成的表面活性剂改性Fe3O4纳米粒子,得到室温下具有流动行为的无溶剂Fe3O4纳米流体,通过FTIR表征流体结构,流体所含无机粒子质量分数为13.1%,Fe3O4纳米粒子呈单分散,粒径为15~20 nm。 |

| Abstract: |
| A gemini cationic quaternary ammonium salt surfactant was synthesized through two-step process with fatty alcohol polyoxyethylene ether(AEO-3)、thionyl chloride and N,N,N',N'-tetramethyl-1,4-diaminobutane. Its structure was characterized by FTIR and H1NMR. Fe3O4 nanoparticles were modified by surfactant synthesized in the previous stage, and the product was solvent-free Fe3O4 nanofluid. The structure of nanofluids was characterized by FTIR. TGA results show that the percent of Fe3O4 nanoparticals is 13.1wt%. TEM image shows that the Fe3O4 nanoparticles have good dispersion and particle size is 15~20 nm. |
