Mechanism and Application of Nickel Nano-Cone by Electrodeposition on a Flexible Substrate
Nano-array structure possesses promising prospect in power supply, optical device and electronic manufacturing. In this paper, a black nickel nano-cone array was prepared on a flexible substrate by galvanostatic deposition and the corresponding factors involved in the fabrication of nickel nano-cone array was explored. Experimental results showed that a large current density and low main salt concentration were not favored to the formation of cone nickel structure. It was also found that ammonium chloride, as the crystal modifier, was crucial to deposit the uniform nano-cone array. In addition, the growth mechanism of nickel nano-cone was further studied by molecular dynamics simulation. The excellent wettability and light absorption of nickel nano-cone array were investigated, which demonstrates potential applications of the nickel nano-cone array.
