Dense copper oxide nanoribbons arrays are prepared on copper sheet using low temperature hydrothermal method. The wettability of the surface modified by stearic acid is superhydrophobic and water contact angle is 153.6°. It is demonstrated that the reversible transition from superhydrophilicity to superhydrophobicity are successfully achieved by heat treatment and re-modification, and the whole process can be accomplished in 170 s. Potentiodynamic polarization curves and Nyquist curves show that this superhydrophobic surfaces have good corrosion resistance and superior durability.

铜板超亲水与超疏水的可逆超润湿转变及其腐蚀性能

使用低温水热法在铜片上制备致密的氧化铜纳米带阵列。硬脂酸改性表面的润湿性为超疏水性，水接触角为153.6°。结果表明，通过热处理和再改性成功实现了从超亲水性到超疏水性的​​可逆转变，整个过程可在170 s内完成。动电位极化曲线和奈奎斯特曲线表明这种超疏水表面具有良好的耐腐蚀性和优越的耐久性。
