Abstract

The invention relates to the technical field of super hydrophobic and oleophobic materials, and discloses a durable Zn-nSiO2 electroplated copper-nickel alloy super hydrophobic and oleophobic material. The durable Zn-nSiO2 electroplated copper-nickel alloy super hydrophobic and oleophobic material comprises following raw materials including copper chloride (II) dihydrate, hexahydrate nickel nitrate, EDTMPS, lauryl sodium sulfate, mixed electroplate liquid, electrolytic cleaning liquid and electrode activation fluid. When Zn<2+> ions of the durable Zn-nSiO2 electroplated copper-nickel alloy super hydrophobic and oleophobic material are subjected to electroplating deposition on the surface of a copper-nickel alloy, a micro-nano rough structure different in size and uneven in distribution isformed, and the copper-nickel alloy material has super-hydrophobic performance. In the copper-nickel alloy surface deposition process, inorganic Zn-nSiO2 particles are formed left and right through covalent bonds and ion bonds via Zn<2+> ions and nano SiO2, the Zn-nSiO2 particles have strong metallic bonds, the attraction force to organic oil dirt is reduced, and meanwhile the Zn-nSiO2 particles have the micro-nano rough structure, oil dirt cannot be attached to the surface of the copper-nickel alloy, and super-oleophobic performance of the copper-nickel alloy material is achieved.

Description

technical field [0001] The invention relates to the technical field of superhydrophobic and oleophobic materials, specifically a durable Zn-nSiO 2 Electroplated copper-nickel alloy superhydrophobic and oleophobic material. Background technique [0002] In recent years, with the continuous improvement of people's quality of life requirements and the increasing awareness of environmental protection and energy conservation, the surface with self-cleaning function has been developed rapidly. A surface that can automatically fall off or be degraded under the action of external forces such as wind, while the surface of superhydrophobic materials has the characteristics of self-cleaning, anti-icing and frosting, corrosion resistance, drag reduction, and high bearing capacity. It is used in military, communication, energy, The environment and other fields have broad application prospects. [0003] However, there are some shortcomings in the surface of ordinary superhydrophobic mat...
