POLYPROPYLENE/CARBON NANOTUBE COMPOSITES, NANOCOMPOSITES THAT THE POLYPROPYLENE/CARBON NANOTUBE COMPOSITES ARE HOMOGENEOUSLY DISPERSED IN POLYPROPYLENE MATRIX, AND PREPARATION METHOD THEREOF

摘要

PURPOSE: A polypropylene / carbon nanotube composite is provided to be dispersed into a polypropylene matrix by improving miscibility with the polypropylene matrix. CONSTITUTION: A polypropylene / carbon nanotube composite comprises a carbon nanotube, and a compound layer containing polypropylene terminal group introduced to the wall of the carbon nanotube. The manufacturing method of the polypropylene / carbon nanotube composite comprises: a step of ultrasonic wave treating the mixture of organic solvent and carbon nanotube grafted by a compound having bromine terminal group; and a step of adding catalyst and polypropylene grafted by a compound having hydroxy group into the mixture, and then stirring the same.
