超长碳纳米管阵列的制备与应用

摘要

Ultralong carbon nanotube arrays, usually referring to those with array heights over 1mm, show great potentials in the development of new structural and electronic composites. Recently, tremendous attention has been poured in the synthesis of ultralong CNT arrays and their growth mechanism. It has shown that the catalytic activity and lifetime of catalysts play important roles in the growth of ultralong carbon nanotube arrays. Concerning on the synthesis of ultralong carbon nanotube arrays, the effects of catalyst structure, growth condition, carbon feedstock and some other factors on the height of carbon nanotube arrays are summarized. And the potential applications of the carbon nanotube arrays have been prospected.%超长碳纳米管阵列通常定义为长度超过1mm的碳管阵列,在新型结构、电子等功能复合材料研发方面具有潜在优势.近期在超长碳纳米管制备和生长机理方面汇集了大量的研究工作,研究表明催化剂的活性和寿命是影响超长碳纳米管阵列生长的决定因素.从催化剂结构、生长条件控制、碳源的选择以及其他因素等方面综述了其对催化剂活性和寿命的影响,以及对超长碳纳米管阵列生长的影响,展望了超长阵列的潜在应用前景.
