摘要

PURPOSE: A manufacturing method of a polymer/carbon nanotube composite is provided to prevent coagulation of carbon nanotubes by rapidly cooling a mixture solution of a polymer and carbon nanotubes, thereby capable of providing a polymer/carbon nanotube composite with improved electrical properties and mechanical properties such as tensile strength. CONSTITUTION: A manufacturing method of a polymer/carbon nanotube composite comprises: a step of manufacturing a mixed solution in which polymer and carbon nanotube is uniformly mixed; a step of spraying the mixed solution with a shape of micro droplet; a step of drying the solution; and a step of collecting a polymer/carbon nanotube composite from the solution during the drying process. In the step spraying the mixed solution with the shape of micro droplet, the mixed solution is sprayed by using an ultrasonic wave sprayer.
