Abstract
ABSTRACTSuperhydrophobic nickel-incorporated carbon-based (Ni/a-C:H) nanocomposite films were prepared successfully on Si substrate via the one-step electrochemical deposition method using methanol as the carbon source and nickel (II) acetylacetonate as the dopant under high voltage, atmospheric pressure and low temperature. Surprisingly, this one-step electrochemical deposited Ni/a-C:H nanocomposite films could achieve superhydrophobic surface. Results showed that without any further modifications by low surface energy materials, the water contact angle of 154.21° and sliding angle of 7.96° were obtained, which attribute to the irregular petaloid structures. In addition, the corrosion resistance tests demonstrated the Ni/a-C:H films deposited at a Ni content of 0.08 mg/ml had excellent corrosion resistance. And the self-cleaning test revealed that the Ni/a-C:H films surface had excellent self-cleaning properties, which indicated this kind of film might have a promising application in the field of drag reduction and self-cleaning.
