Description

technical field [0001] The invention relates to the technical field of carbon nanotubes, in particular to a PBAT carbon nanotube fiber and a method for reinforcing the carbon nanotube fiber. Background technique [0002] Carbon nanotube fiber is a new type of high-performance fiber material, which is extracted from carbon nanotube arrays. The diameter of its single strand fiber is usually several microns, which cannot be directly applied. Therefore, relevant technical personnel have developed an array spinning method. , solution spinning method, chemical vapor deposition spinning method and other special spinning processes to make carbon nanotube fiber materials, which have far more than conventional application effects in the fields of high energy absorption and high strength. [0003] CN109563649A relates to a method for preparing carbon nanotube fibers and carbon nanotube fibers prepared thereby, the method comprising: preparing carbon nanotube aggregates (S1) from a carb...
