摘　　要：利用微乳液技术,在三苯基磷和CTAB及含硫离子液体3-甲基-1-[6-(N,N-二丁基二硫代氨基甲酸酯)-己基]-咪唑六氟磷酸盐(ILS)的存在下,以硼氢化钠为还原剂,制备含硫离子液体单分子层表面修饰的铜纳米颗粒.利用TEM、Uv-vis、FTIR对所得铜纳米颗粒进行表征.结果表明,含硫离子液体能在纳米铜颗粒表面形成较紧密的吸附层,有助于提高铜纳米颗粒的稳定性,得到较小粒径的纳米颗粒.By using microemulsion technology and taking 3-methyl-l-[6-（N, N-dibutyl-amino-dithiocarbamates）-hexyl]-imidazolium hexafluorophosphate as a modification agent and NaBH4 as reductive agent, the copper nanoparticles modified on the surface of monomolecular layer of sulphurie-ion-containing liquid was prepared in the presence of PPh3 and CTAB. The stability and radius of copper nanoparticles prepared were studied with TEM, Uv-vis, and FTIR. It was found that the sulphuric containing ionic liquid could lead to the formation of compacted absorbance layer, improving the stability and decreasing the radius of copper nanoparticles.
