摘　　要：采用拉脱圆环法测量乙酸锌水溶液表面张力σ与浓度c之间的关系,用Originpro8软件解析了σ-c关系曲线。结果表明,乙酸锌水溶液表面张力σ在浓度为0.1~1.3 mol/L时呈减小趋势。根据吉布斯理论和与NaCl溶液σ-c关系曲线,表明乙酸锌水溶液具有表面活性物质特性。Zinc Acetate is main material to prepare ZnO thin films by ultrasonic spray pyrolysis.Surface tension of Zinc acetate solution is one of important process parameters.The relationship of surface tension σ and concentration c of Zinc acetate solution is obtained by pull off ring.The σ-c curve is analyzed by Oringinpro 8 software.The results show that surface tension σ decreases with increasing concentration c within 0.1~1.3mol/L.According to the Gibbs theory and the comparison with the σ-c curve of NaCl solution,Zinc acetate solution behave surfactant properties.
