| 摘 要： | 采用电沉积法在碳钢片表面制备Cr2O3微纳膜层，并用硬脂酸对其进行表面修饰降低其表面能。通过单因素法依次优化电流密度、铬酸浓度、极间距和电沉积时间，并分析所得Cr2O3超疏水膜层的表面形貌和润湿性。当电流强度为4A、铬酸浓度为1.5 mol/L、极间距为5 mm及电沉积时间为1 h时，经硬脂酸修饰后Cr2O3膜层的超疏水性能优异，其静态接触角达到153.52°且滚动角为2.17°。

| Abstract: | The micro/nano film of Cr2O3 was prepared on the surface of carbon steel sheet by electrodeposition method, then its surface energy was reduced by surface modification with stearic acid. The current density, the chromic acid concentration, the electrode spacing and the time of electrodeposition were optimized by single factor method, while the surface morphology and wettability of the obtained superhydrophobic films were analyzed. When the current intensity is 4A, the concentration of chromic acid is 1.5 mol/L, the electrode spacing is 5 mm and the electrodeposition time is 1 h, the superhydrophobic performance of the Cr2O3 films modified by stearic acid is excellent while the static contact angle reaches 153.52° and the rolling angle is 2.17°. |
