METHOD FOR MANUFACTURING CONDUCTIVE POLYURETHANE RESIN COMPOSITE IN WHICH CARBON NANO TUBE IS UNIFORMLY DISPERSED

摘要

PURPOSE: A manufacturing method of a conductive polyurethane resin composite is provided to not generate problem in long term durability and degradation of physical properties of a final product due to addition of a dispersant. CONSTITUTION: A manufacturing method of a conductive polyurethane resin composite comprises a step of forming a mixture by mixing carbon nanotube and polyol; a step of dispersing the carbon nanotube into the polyol. The dispersion step comprises: a step of ball-milling the mixture; a step of ultrasonic wave treating the mixture; and a step of roll milling the mixture. The carbon nanotube does not generate functional groups except carbon by a chemical pretreatment. The polyol composition does not comprise a dispersant for dispersing the carbon nanotube.
