Method for enhancing tensile strength of carbon nanotube fiber aggregate
The present invention relates to a method for enhancing tensile strength of a carbon nanotube (CNT) fiber aggregate, comprising dispersing a CNT fiber aggregate with chlorosulfonic acid (CSA), followed by thermal treatment, wherein a particular magnitude of tension is applied upon the thermal treatment, whereby the CNT fiber aggregate is increased in alignment level and tensile strength.
