摘　　要：溶液涂镀镀层技术中,镀液的润湿性能对镀层纳米粒子在基体上的分布均匀性起着至关重要的作用。本研究在制备了含Pd纳米粒子的镀液基础上,考察了6种表面活性剂,即聚乙烯吡咯烷酮、油酸、油胺、十二硫醇、十六烷基三甲基溴化铵、十二烷基苯磺酸钠等对涂镀液的表面张力及在Cu基体上润湿角的影响,并利用扫描电镜对形成的镀层中Pd纳米粒子的分布以及镀液中Pd纳米粒子的含量对镀层的影响进行了表征。实验结果表明,在所研究的六种添加剂中,十二烷基苯磺酸钠可以显著降低含Pd镀液的表面张力和在Cu基体上的接触角,在其添加量为560 mg/L和镀液含Pd量为60 mg/L时,可在基体表面形成均匀分布的Pd镀层。The wettability of the coating solution plays an important role in the uniformity of the coating metal nanoparticles on the substrate.Based on the preparation of coating solution contained Pd nanoparticles,the effects of six surfactants,namely,polyvinylpyrrolidone,oleylamine,oleic acid,1-dodecanethiol,cetyltrimethylammonium bromide,and sodium dodecyl benzene sulfonate,on the surface tension of the coating solution and the contact angle on Cu substrate were investigated.At last,the distribution of Pd nanoparticles of the coating layer was characterized by SEM.The experimental results show that among the six additives,the addition of SDBS can significantly reduce the surface tension and contact angle of the coating solution on Cu substrate,and the uniform Pd coating can be formed on the surface of the substrate when the concentration of the added sodium dodecyl benzene sulfonate is 560 mg/L and the content of Pd nanoparticles in the coating solution is 60 mg/L.
