PET COMPOSITION FILLED IN SURFACE MODIFIED MULTI WALLED CARBON NANOTUBE AND MANUFACTURING METHOD THEREFOR

摘要

A polyethylene phthalate/carbon nanotube nanocomposite and a method for preparing the polyethylene phthalate/carbon nanotube nanocomposite are provided to improve mechanical properties by enhancing the reactivity between a polyethylene phthalate resin and a carbon nanotube. A polyethylene phthalate/carbon nanotube nanocomposite comprises 100 parts by weight of polyethylene phthalate; and 0.5-2 parts by weight of a surface treated carbon nanotube, wherein the surface-treated carbon nanotube has a long chained reactive group by the treatment of an acid and the reaction with 1,10-diaminodecane. The nanocomposite is prepared by mixing a polyethylene phthalate/carbon nanotube nanocomposite with a catalyst; and reacting them by transesterification at 190 deg.C for 1 hour and at 230 deg.C for 2 hours and by condensation at 280 deg.C in vacuum.
