Method for producing reinforced carbon nano pipeline adopting fiber yarns as carriers

Abstract

The invention refers to a method for producing reinforced carbon nano pipeline adopting fiber yarns as carriers. The method comprises the following steps: dissolving carbon nano pipes in an organic solvent, and performing ultrasonic dispersion to obtain a carbon nano pipe suspension; electrifying two cone-shaped poles outside a container containing the suspension to form an uneven electric field, feeding the dried fiber yarns into the suspension at a constant speed, and moving the dried fiber yarns in the suspension at a constant speed; lifting the fiber yarns at a constant speed to leave off the liquid surface of the suspension and pass through corresponding small holes on a filtering plate; filtering the redundant carbon nano pipes which are absorbed at the outsides of the fiber yarns; and coating a polymer at outsides of the fiber yarns in a packing tool of the polymer leads so as to obtain the reinforced carbon nano pipeline adopting the fiber yarns as the carriers. The method provided by the invention has the following characteristics: the high-voltage uneven electric field can quickly induce the carbon nano pipes to be combined with the fiber yarns; and because the fiber yarns with good tensile strength and toughness are taken as the carriers of the carbon nano pipes, the fiber yarns can be quickly operated in the production process, and the method provided by the invention is higher in working efficiency.

Description

Technical field [0001] The invention belongs to the technical field of processing carbon nanotubes, in particular to a method for manufacturing carbon nanotubes. Background technique [0002] Carbon nanotubes have been hailed as future materials since they were discovered, and they are one of the frontier fields of international science in recent years. Some interesting features of carbon nanotubes make them potentially useful in many fields. Due to their useful properties, carbon nanotubes are currently used in the manufacture of carbon nanotube articles, such as carbon nanotube wires or carbon nanotube bundles. [0003] However, current carbon nanotube wires have poor mechanical strength, such as brittleness and breakage when external mechanical force is applied. This is because the carbon nanotubes of the carbon nanotube wire are formed by adhering to each other through relatively weak van der Waals forces. Thus, there is a need to increase the mechanical strength of c...

Problems solved by technology

But the speed of forming the carbon nanotube wire is very slow, about 2mm / min to about 5mm / min

And the length of production is limited: one is due to the limitations of its production equipment, and secondly, it is taken out from the carbon nanotube colloid solution with a metal tip, and the strength of the formed carbon nanotube line is insufficient. Fracture (the length disclosed in the specification is several centimeters to tens of meters)

Obviously this kind of carbon nanotube wire is not suitable as a long-distance wire
