| 摘 要： | 纳米材料的制备、性能与应用已成为近年来的研究热点之一犤１犦。由于在催化、光学和电学材料中的广泛应用，超细单分散的金属微粒的制备与性质已引起人们的广泛兴趣。通常制备金属纳米微粒的方法有两种：一是把固体金属材料分裂为纳米尺寸的颗粒，如机械粉碎、电弧放电及金属原子蒸气沉积犤２犦，用这种方法制备的金属微粒粒径一般都比较大，且粒子尺寸分布宽，另一种是把金属原子制成纳米尺度的颗粒，如乳液聚合法犤３犦、热解犤４犦、γ－射线辐照犤５犦、脉冲电沉积犤６犦和化学还原犤７犦等，这种方法制备的微粒粒径通常分布窄且粒子小…

| Abstract: | Pyridinium dioctadecyldithiophosphate(PyDDP) modified nickel nanoparticles were prepared by chemical re-duction method in water-toluene mixing solution. By using FT-IR, TG, XRD and TEM, the resultant surface modified Ni particles were characterized. The results show that the nano-Ni core has an average diameter of 12nm with a fcc structure. The hydrophobic groups formed by the organic layer on the surface of Ni particles make the nanoparticles have good stability and oil-solubility. |
