【摘要】 碳纳米管具有潜在的超高强、高导电和其它多功能特性。将碳纳米管制备成连续纤维是实现其宏观应用的关键。目前,制备连续碳管纤维的方法有液相湿纺、阵列干纺等后续处理法和化学气相反应直接纺丝法。综述了这些制备方法和相关纤维性能的研究进展,着重阐述了化学气相反应直接纺丝法的原理、过程特点、纤维性能和最新研究进展。采用直接化学气相反应纺丝法,通过改进的反应系统,可达到连续稳定纺制可解析无粘连的连续碳纳米管纤维。该方法过程简单,可一步制备出连续碳管纤维,具有工业化发展前景。更多还原

【Abstract】 Carbon nanotubes (CNTs) are potentially ultrastrong,highly electrical conductive,and have many other functional properties.The fabrication of continuous CNT fiber is the critical step towards their macro- scopic applications.Several methods have been under development in the fabrication of continuous CNT fibers, including the solution spinning,dry-spinning and the direct chemical vapor deposition (CVD) spinning process. This paper provides an overview of these methods and the relevant fiber properties,with the emphasis on the direct CVD spinning process,including our recent progress made in the control of the spinning by using improved reaction designs.更多还原
