Abstract
In this study, a new method is introduced for fabricating carbon nanotube (CNT) paper, in which the solvent is sprayed on the CNT sheet while it is wound on a rotating mandrel. As the solvent evaporated, the capillary force pulls CNT closer together, resulting in a CNT paper with a high degree of alignment and a high packing density. Three batches of multi-walled CNTs with different wall thicknesses, tube diameters and lengths are utilized for synthesizing highly oriented CNT papers. It is found that CNTs with smallest diameter of 8Â nm form strongest CNT paper with a tensile strength of 563Â MPa and a tensile modulus of 15Â GPa, while that made with CNTs of 10Â nm diameter shows the highest electrical conductivity of 5.5Â ÃÂ 104Â S/m.
