Example Embodiment

[0033] Example 1

[0034] Such as figure 2 As shown, the carbon nanotube fiber composite wire of the present invention takes the carbon nanotube fiber as the main body, and obtains a uniform metal coating on the surface of the carbon nanotube fiber through an electroless plating process. The specific steps include the preparation of carbon nanotube fibers and the chemical plating of the fibers.

[0035] First, use the electron beam evaporation method, with thermally oxidized SiO in 2 inches 2 A uniform Fe film is deposited on the Si wafer as a catalyst for the growth of carbon nanotube arrays. Then, it was placed in a quartz tube furnace with a diameter of 3 inches, and acetylene gas was used as a carbon source gas to prepare a spinnable carbon nanotube array using thermal chemical vapor deposition technology under 700°C growth conditions. The array height was 400 μm. Afterwards, a carbon nanotube film with a fixed width of 3mm is uniformly drawn from the spinnable array through ...

Abstract

The invention discloses composite conductor application of carbon nano tube fiber and a preparation method thereof. The invention is characterized in that a high strength carbon nano tube fiber material is combined with electroplating or chemical plating surface treatment process, and conductive metal coating is compounded on the carbon nano tube fiber, thus obtaining a carbon nano tube composite conductor with light weight, high strength and high electric conduction. The preparation method includes the following steps: firstly high strength carbon nano tube fiber material is prepared, and then chemical plating or electroplating is adopted to prepare uniform metal coating on the surface of fiber, thus obtaining the carbon nano tube composite conductor. The type of metal coating and the thickness of metal coating are controlled, so that the conductivity of carbon nano tube conductor can be consistent with the conductivity of metal body. The application and preparation method of the invention are simple and feasible, step is simple, and repeatability is good, thus being applicable to mass production, thereby having significance in development of novel superfine conductor with light weight, high tenacity and high strength and in showing potential application value thereof in electronic industry.

Description

technical field [0001] The invention relates to the field of application and preparation of nanomaterials, in particular to the application of light-weight and high-strength carbon nanotube fibers to composite wires and a preparation method thereof. Background technique [0002] Carbon nanotubes have been observed by Ijima under the electron microscope since 1991 [1] , has attracted the attention of scientists. Further studies have shown that carbon nanotubes have excellent mechanical properties and good electrical conductivity due to their special graphite layered structure. The current research results show that the tensile strength of carbon nanotubes is 150Gpa [2] , Young's modulus is 1Tpa [3] . In recent years, through spinning technology, carbon nanotube aerosol [4] , Spinnable carbon nanotube arrays [5] and cotton-like carbon nanotube raw materials [6] The carbon nanotube fiber material composed of pure carbon nanotubes was obtained through processing. At pres...
