Wettability of stearic acid modified chrome oxide layer on copper substrate.

A micronano structure superhydrophobic film was fabricated on copper substrate by electrodeposition of chrome oxide layer and surface modification of stearic acid. The fabricated film shows high water contact angle (165.4°) and low sliding angle (1.8°), and also performs well at corrosion resistance (protection efficiency, 99.9989%). The surface was characterised by scanning microscope, X-ray photoelectron spectroscope and atomic force microscope. [ABSTRACT FROM AUTHOR]
