Abstract

The invention discloses Schiff base metal complex modified carbon nano-tubes. The additive at least comprises a Schiff base copper complex with a structure represented by a general formula (I) shown in the description as a modification compound, and carbon nano-tubes serve as a modified matrix. A preparation method mainly comprises the following steps: 1) synthesis of the Schiff base copper complex, 2) acidizing of the carbon nano-tubes, and 3) ultrasonic compounding treatment and the like of acidized carbon nano-tubes in an acidification THF solution of the Schiff base Cu complex. According to the Schiff base metal complex modified carbon nano-tubes, the condition that the Schiff base copper complex is adopted to carry out surface modification on the carbon nano-tubes is proposed for thefirst time, the weak point that the carbon nano-tubes are prone to aggregated bundled winding, relatively inert in surface, relatively low in dispersity in common organic solvents and the like is improved, and the applicability of the carbon nano-tubes in the fields of lubricating oil additives and polymeric wear-resistant material additives is improved; and the involved raw materials are simple in source, the preparation process is simple, and the cost is low, so that the carbon nano-tubes are applicable to popularization and application.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil additives, and in particular relates to a Schiffer's alkali copper complex modified carbon nanotube and its preparation method and application. Background technique [0002] As a one-dimensional nanomaterial, carbon nanotubes are light in weight, perfectly connected in a hexagonal structure, and have many special mechanical, electrical and chemical properties. In recent years, with the in-depth research on carbon nanotubes and nanomaterials, their broad application prospects have been continuously shown. Using the excellent properties of carbon nanotubes, many composite materials with excellent performance can be produced. For example, plastics reinforced with carbon nanotube materials have excellent mechanical properties, good electrical conductivity, corrosion resistance, and can shield radio waves. The ceramic composite material reinforced with carbon nanotubes has the advantages of h...
