One-step fabrication of a superhydrophobic copper surface by nano-silver deposition

Abstract

A bionic superhydrophobic coating with good corrosion resistance was prepared by one-step nano-silver deposition on a copper substrate. The superhydrophobic surface was covered with petal-like and coral-like micro/nano-structures. With the highest water contact angle of 169.9°, the superhydrophobic coating has good superhydrophobicity. The surface morphology, chemical composition, and wettability of the samples were characterized by scanning electron microscopy, Fourier transformed infrared, x-ray diffraction, and water contact angle measurement. The corrosion resistance tests showed a significant improvement on the superhydrophobic sample.

Superhydrophobic modified electrodeposited copper surface for fog harvesting

“…19 Simultaneous deposition of silver and modifying the surface with perfluorooctanoic acid by immersion method also led to Ca of 169.9°. 20 Electrodeposition stands out as a well-established industrial process that can be used in superhydrophobic surface fabrication due to its facility, scalability, and high efficiency. Various metals, including nickel, 21 nickel graphite, 12 zinc, 22,23 and copper 24,25 have been successfully deposited for this purpose.…”

Novel and facile method for fabrication of robust superhydrophobic film on copper surface and its chemical, mechanical, and corrosion performance

“…Owing to its high thermal conductivity, high electrical conductivity, low chemical reactivity, mechanical workability, and pleasing appearance, copper is an essential material in the industry. Copper is widely used in many applications, including chemical and microelectronics, printed circuit boards in electrical instruments, condenser, heat exchanger conductors, various instruments of the elastic element, pumps, tubing, medical equipment, decorative, optical instruments, electrical power line conductors, and domestic and industrial water utility pipelines [1][2][3][4][5]. Copper metal corrodes differently depending on the environment, so controlling copper corrosion is one of the most difficult challenges in copper applications.…”
