Abstract： |
Production of carbon nanometer-tube array is carried out by providing basis with shielding layer, providing catalyst evaporator source, rotating basis along rotating axis, forming thickened-gradient catalyst thin-film on basis, eliminating shielding layer, defining a catalyst regional block on catalyst thin-film, thinning the thickness of catalyst regional block from the first end to the second end while reaching the optimum thickness in the range of the first end and the second end, treating the catalyst regional block into catalyst granular array, inducing into carbon source gas, growing carbon nanometer-tube array by CVD method and bending the carbon nanometer-tube array in the optimum thickness direction reversely. It can reach local multi-direction growth of carbon nanometer-tube array. |
