POLYPROPYLENE-GRAFT-MALEIC ANHYDRIDE/CARBON NANOTUBE NANOCOMPOSITES WITH EXCELLENT THERMAL STABILITY AND ELECTRICAL CONDUCTIVITY

摘要

PURPOSE: A method for preparing polypropylene-graft-maleic acid anhydrite/carbon nanotube nanocomposite is provided to improve dispersibility in a polymer matrix by acidifying a multiwall carbon nanotube(MWCNT). CONSTITUTION: A method for preparing polypropyelene-graft-maleic acid anhydrite/carbon nanotube nanocomposite comprises a step of acid-treating carbon nanotube to fuse a carbon nanotube and polypropylene-graft-maleic acid anhydrite. The carbon nanotube contains 0.01-50wt% of a carboxylic group. The polypropylene-graft-maleic acid anhydrite contains 0.01-10 wt% of maleic acid anhydrite.
