MANUFACTURING METHOD OF CARBON NANOTUBES/POLYOLEFIN COMPOSITES WITH SUPERIOR MECHANICAL PROPERTIES

摘要

PURPOSE: A manufacturing method of a carbon nanotubes/polyolefin composite is provided to improve dispersity of carbon nanotube in polyethylene by chemically surface-treating carbon nanotubes, thereby being capable of manufacturing a carbon nanotube/polyolefin composite material with excellent mechanical and physical properties. CONSTITUTION: A manufacturing method of a carbon nanotubes/polyolefin composite comprises: a purification step removing impurities comprised in carbon nanotubes; a step of chemically surface-treating the carbon nanotubes; a step of melt-mixing the chemically surface-treated carbon nanotubes with a polyolefin resin. The polyolefin is polypropylene or polyethylene. The carbon nanotube/polyolefin composite material contains 0.1-10 parts by weight of carbon nanotube based on 100.0 parts by weight of total composite material.
