Decoupling the growth and the application of nanomaterials by transfer is an important issue in,nanotechnology. He, we developed an efficient transfer technique for carbon nanotube (CNT) arrays by using ice as a binder to temporarily bond the CNT array and the target substrate. Ice Makes it an ultraclean transfer because the,evaporation of ice ensures that no contaminants are introduced The transferred,superaligned carbon nanotube (SACNT) arrays not only keep their original appearance and initial alignment but also inherit their spinnability, which is the most desirable feature. The transfer-then-spin-strategy can be employed to fabricate patterned CNT arrays, which can act as 3-dimensional electrodes in CNT thermoacoustic chips, Besides, the flip-chipped CNTs are promising field electron emitters. Furthermore,, the ice-assisted transfer technique provides a cost-effective solution, for mass production of SACNTs, giving CNT technologies a competitive edge and this method may inspire new ways to transfer other nanomaterials.
