Investigations of Smooth Function of Polyethylene Glycol Surfactants on the Electrolessly Deposited Silver Film

　应用原子力显微镜技术及开路电位～时间谱技术,研究了非离子表面活性剂聚乙二醇2000,6000,20000对硅(100)表面无电沉积银膜的光滑作用.实验表明硅(100)表面无电沉积银的光滑程度以及镀层的质量均随聚乙二醇聚合度的增加而变好.Some non_ionic surfactants of Polyethylene Glycol 2000,6000 and 20000 were used to estimate the smooth affection on the electrolessly deposited silver film. The adsorption state of the surfactants about Si/solution interface was investigated by using open circuit potential_time technology (Op_t).As comparative experiments, the atomic force microscopy (AFM) was also performed to study the surface smooth effection of the surfactants. It was found that with the increasing of the carbon chain in the surfactants, the smooth effection is getting great. PEG 20000 showed the best smooth function.作者联系地址：兰州大学化学化工学院,兰州大学化学化工学院,兰州大学化学化工学院,兰州大学化学化工学院,兰州大学化学化工学院 甘肃兰州730000 ,甘肃兰州730000 ,甘肃兰州730000 ,甘肃兰州730000 ,甘肃兰州730000Author's Address: College of Chemistry and Chemical Engineering,Lanzhou University,Lanzhou 730000, Chin
