    • A method and apparatus for continuously synthesizing oriented carbon nanotubes, with which oriented carbon nanotubes can be stably synthesized in large quantities, is presented.The method and apparatus for continuously synthesizing oriented carbon nanotubes comprise: a coating and drying step in which a catalyst liquid is applied and dried to form a catalyst layer on a substrate surface; a catalyst substrate formation step in which the catalyst layer is heated to form a catalyst substrate having a catalyst particle layer on the substrate surface; a synthesis step in which a raw material gas heated to a temperature equal to or higher than a synthesis temperature for the oriented carbon nanotubes is brought into contact with the surface of the catalyst substrate to synthesize oriented carbon nanotubes; and a collection step in which the oriented carbon nanotubes are collected. In the synthesis step, a carrier gas having a temperature equal to or higher than the synthesis temperature is supplied to the periphery of the raw material gas which is in contact with the surface of the catalytic substrate, or to its front and rear stages. Thus, oriented carbon nanotubes are continuously or intermittently synthesized.
    • 提出了一种用于连续合成定向碳纳米管的方法和装置,其中定向碳纳米管可以大量稳定地合成。 用于连续合成定向碳纳米管的方法和装置包括:涂覆和干燥步骤,其中施加和干燥催化剂液体以在基材表面上形成催化剂层; 催化剂基板形成步骤,其中催化剂层被加热以形成在基板表面上具有催化剂颗粒层的催化剂基材; 将加热到等于或高于取向碳纳米管的合成温度的原料气体与催化剂基板的表面接触以合成定向碳纳米管的合成步骤; 以及其中收集定向碳纳米管的收集步骤。 在合成步骤中,将具有等于或高于合成温度的温度的载气供给到与催化剂基材的表面接触的原料气体的周边或其前后级。 因此,定向碳纳米管是连续或间歇合成的。
