Abstract

The invention discloses a plating solution and method for chemically plating Ni-P on the surface of a carbon nano tube. The chemical plating solution is characterized by comprising 18-34 g / L of nickel sulfate (NiSO4.6H2O), 10-20 g / L of citric acid (C6H8O7.H2O), 15-25 mL / L of lactic acid (C3H6O3), 8-16 g / L of anhydrous sodium acetate (CH3COONa), 20-30 g / L of sodium hypophosphite (NaH2PO2.H2O) and 80-120 mL / L of anhydrous alcohol (C2H5OH). The chemical plating method comprises the steps that the carbon nano tube is soaked into the anhydrous alcohol and subjected to alkaline washing and acid pickling, then, the carbon nano tube is put into the chemical plating solution, plating is conducted by controlling the PH value and the temperature, and the Ni-P is deposited onto the surface of a substrate of the carbon nano tube to form a plating layer. According to the plating solution and the method, operation and implementation are easy, and the economical efficiency is good. The carbon nano tube is expected to achieve appropriate-strength interfacial adhesion in an aluminum base composite material, and Al4C3 is effectively inhibited from being generated too much.

Description

technical field [0001] The invention relates to a preparation process for electroless Ni-P plating on the surface of carbon nanotubes, in particular to a Ni-P plating solution formula and a plating method for the surface of carbon nanotubes, belonging to the field of carbon nanotube surface technology. Background technique [0002] Carbon nanotubes have excellent mechanical properties, high chemical stability and unique electrical properties. However, low-dimensional nanomaterials have many defects and poor dispersion. In particular, the surface structure of carbon nanotubes often affects many properties such as electricity, mechanics, and optics. In order to improve the surface structure of carbon nanotubes, coating methods are generally used to improve or change the dispersion, stability and interaction with other substances of nanotubes. Compatibility, which allows it to obtain new physical, chemical and mechanical properties. [0003] In order to give full play to the ...
