【摘要】 采用红外-紫外-可见分光光度计法研究了不同表面活性剂、配位剂、纳米SiO₂和p H对纳米粒子在溶液中的分散性和稳定性的影响;讨论了在不同温度和纳米粒子含量下,纳米粒子在铜表面的沉积速度。实验结果表明,化学复合镀Ni-P合金最佳工艺及操作条件是表面活性剂为5 g/L十二烷基硫酸钠,配位剂为13 g/L醋酸钠,2 m L/L乳酸,p H为5.0⁵.5,3 g/L纳米SiO₂,θ为80⁸5℃。更多还原

【Abstract】 The effects of different surfactants,ligands,nano-SiO₂ and p H on the dispersity and stability of the nano-particles in the aqueous solution were studied by infrared-ultraviolet-visible spectrophotometry.The plating velocity of the nano-particles on the surface of Cu substrates were discussed at different temperatures and contents. The experimental results showed that the optimal process and operating conditions of electroless composite plating Ni- P alloys were obtained,including SDS as surfactants（ 5 g / L）,Na Ac as ligands（ 13 g / L）,lactic acid（ 2 m L / L）,p H（ 5. 0 5. 5）,nano-SiO₂（ 3 g /L） and temperature（ 80 ⁸5 ℃）.更多还原
