摘要
碳纳米管(CNTs)是一种拥有巨大应用前景的纳米材料,但较低的产能和高昂的造价限制了其广泛应用。目前,批量制备碳纳米管普遍采用的是流化床催化化学气相沉积法(CVD)。综述了制备碳纳米管过程中,碳纳米管独特的团聚现象及流化特性,近年来碳纳米管颗粒流化的实验和理论研究,以及碳纳米管流化增强的方法,并提出未来较有价值的研究方向。
Carbon nanotubes(CNTs)are a kind of nanomaterials with great application prospects,but their wide application is limited by their low production capacity and high cost.At present,the most suitable method for batch preparation of CNTs is fluidized bed catalytic chemical vapor deposition(CVD).The unique aggregation phenomenon and fluidization characteristics of CNTs in the preparing process,the experimental and theoretical research on fluidization of CNTs particles in recent years,and the methods of enhancing fluidization of of CNTs were reviewed.The more valuable research directions in the future were put forward.
