Problems solved by technology

However, the plasma-assisted chemical vapor deposition method requires the additional use of a plasma-generating vacuum system, resulting in a higher cost; the thermal chemical vapor deposition method has the advantages of large growth area and low cost, but it requires strict reaction conditions. It has the disadvantage that the reaction parameters are difficult to control, so it is difficult to achieve the growth of aligned carbon nanotube arrays

The device includes the following parts: one reactor; a cocurrent power supply which has positive pole and negative pole; the first metal plate (located in the reactor) connecting to the positive pole of the power supply; the second metal plate (parallel to the first metal plate) connecting to the negative pole; the basal body between the first and the second metal plate, the surface that can produce catalyst is opposite to the second plate. The invention also disclosed a way to produce carbon nanometer pipe array with the device. The device in the invention demands low cost; besides, it can easily realize the direction-located development of the carbon nanometer pipe array.

Description

【Technical field】 [0001] The invention relates to the technical field of nanometer materials, in particular to a device and method for directional growth of carbon nanotube arrays. 【Background technique】 [0002] Carbon nanotubes are seamless nanoscale cylinders formed by curling single-layer or multi-layer graphite sheets according to a certain helicity. Since the radial direction of carbon nanotubes is subject to the confinement effect of the nanoscale, it is a standard one-dimensional quantum wire. , which can exhibit many quantum mechanical effects; and with the change of the helicity of carbon nanotubes, it can exhibit metallic or semiconducting properties, etc. Due to the unique characteristics of carbon nanotubes, it has broad application prospects in various disciplines. [0003] Traditional carbon nanotube growth methods include arc discharge method, laser evaporation method and chemical vapor deposition method. The arc discharge method uses gas discharge to conve...
