Description
Technical field
But the present invention relates to a kind of preparation method of big area spinning carbon nano pipe array, belong to field of nano material preparation.
Background technology
Carbon nanotube (CNT) has excellent mechanical property: its tensile strength reaches 50～200GPa, is 100 times of steel, and density but has only 1/6 of steel, and the theoretical Young's modulus of carbon nanotube can reach 1TPa, thereby is called as " super fiber ".Carbon nanotube has excellent conducting performance in addition, because its special graphite laminate structure presents different electrical properties and conductive capability, but and electricity modulating performance with excellence.Therefore, adopt carbon nanotube to make up the important directions that novel mechanics, electricity, optical function device become the carbon nanomaterial development.
In recent years, people are obtaining the progress of advancing by leaps and bounds aspect controlled preparation of carbon nanotube and the package technique.Wherein the carbon nano pipe array material has been subjected to people's extensive concern owing to having consistent self-assembly orientation characteristic, has obtained progress in the application facet of preparation of carbon nano pipe array device and matrix material.2002, but China's model is kept kind academician research group and has been reported first on the Nature magazine with vertical spinning carbon nano-pipe array and classify the basis as, can carry out continuous spinning to the solid carbon nano-tube array, process a kind of filamentary material that constitutes by pure nano-carbon tube, started the frontier [document 1] of carbon nano-tube material package technique research.
At present, but generally adopting acetylene and ethene aspect the preparation of spinning carbon nano pipe array is carbon-source gas [document 1,2], is catalyzer with the metallic particles at the bottom of the silicon wafer-based, method by thermal chemical vapor deposition (TCVD) is prepared, and is called acetylene CVD method and ethene CVD method.But the spinning of acetylene gas preparation at present carbon nano pipe array technology has obtained breakthrough, but China's model is kept the preparation that the Baughman research group of the kind study group and the U.S. has realized the spinning carbon nano pipe array, and further amplify, but realized the preparation of large-area high-quality spinning carbon nano pipe array to the array aufwuchsplate is long-pending.Processed carbon nano-tube film by the way of dry-spinning on this basis, and successively be applied to the preparation of loud speaker [document 3], transparent conductive film [document 4], artificial-muscle carbon nanotube functional devices such as [documents 5], showed very application prospects of this material.But and aspect ethene CVD preparation spinning carbon nano pipe array, people such as Li Qingwen are by the improvement to catalyst structure, realized overlength (greater than 1mm) but the preparation of spinning carbon nano pipe array, and processing has obtained high-intensity carbon nano-tube fibre material [document 6].Yet up to the present, but aspect ethylene gas preparation spinning carbon nano pipe array, the large-area preparation technology still achieves no breakthrough, and does not more realize the membrane technology of carbon nano pipe array.
In addition, but with respect to acetylene CVD preparation spinning carbon nano pipe array, the catalyst structure that ethene CVD growth is adopted is more complicated, growth temperature is higher, and therefore the nucleation process of granules of catalyst and activity of such catalysts, life-span are different from acetylene CVD array preparation in the catalyst pretreatment process.Simultaneously, also there are very big-difference in the split product of ethylene gas and acetylene gas split product, have caused the difference of tube wall number, caliber, defect concentration and physics, the chemical property etc. of two kinds of carbon-source gas carbon nanotubes grown thus.But therefore adopt ethene CVD growing large-area spinning carbon nano pipe array material, existing the potential using value aspect the preparation of carbon nanotube functional device.
