Abstract
The present invention provides a process for preparing a carbon nanotube sheet, which comprises forming carbon nanotubes; aggregating the carbon nanotubes to form a yarn; treating the yarn with a solvent to enhance the aggregation force; winding the solvent-treated yarn to prepare a sheet preform having a structure in which one yarn is continuously wound; and cutting and/or pressing the sheet preform to prepare a carbon nanotube sheet that comprises an arrangement structure in which one or a plurality of yarns are uniaxially aligned, and a carbon nanotube sheet prepared thereby.
