(SWCNTs) can be produced in large quantities by three dominant techniques: arc discharge [1], lar ablation [2], and chemical vapor deposition (CVD, including high-pressure carbon monoxide (HiPco) process) [3]. SWCNTs synthesized by different methods always have different diameter and chirality. Using density gradient ultracentrifugation, we can obtain CNT samples with the similar diameter or the same chirality [4-7]. Double-walled carbon nanotubes (DWCNTs), consisting of two concentric graphene cylinders, are the simplest member of multi-walled carbon nanotubes (MWCNTs), and have more excellent electronic, thermal and mechanical properties than SWCNTs. Many attempts have been made for synthesizing high pure DWCNTs, such as conventional arc discharge [8], high-temperature puld arc discharge [9], high-temperature annealing of peapods [10], and chemical vapor deposition (CVD) [11]. Furthermore, the density gradient ultracentrifugation (DGU) has been also ud to parate DWCNTs from SWCNTs [12]...此处还有三段话,省略 A multidisciplinary approach and the planned activities 总述 1.
