POLYURETHANE FOAM-CARBON NANOTUBE COMPOSITE, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a polyurethane foam-carbon nanotube composite. The polyurethane foam-carbon nanotube composite according to the present invention comprises polyurethane and a carbon nanotube, and the content of the carbon nanotube is 0.01-7 parts by weight on the basis of 100 parts by weight of a polyol. The carbon nanotube contained in the polyurethane foam-carbon nanotube composite of the present invention can reduce the size of foamed cells by acting as a nucleating agent of foamed cell formation and can reduce thermal conductivity of the composite. Therefore, the polyurethane foam-carbon nanotube composite of the present invention additionally provides electrical characteristics while maintaining the mechanical characteristics of known polyurethane foams and remarkably improves thermal insulation characteristics.
