CARBON NANOTUBE-STEREOCOMPLEX POLYLACTIDE COMPOSITE MATERIAL

摘要

The present invention relates to a carbon nanotube-stereocomplex polylactic acid composite material which improves conductivity properties by improving connectivity of a carbon nanotube using a polylactic acid stereocomplex crystal. According to the present invention, the composite material enables to be widely used for a material which needs conductivity as enabling to gain electrical conductivity maximized by the small amount of the carbon nanotube. The present invention comprises: the stereocomplex polylactic acid acquired by forming a crystal by mixing L-polylactic acid and D-polylactic acid with 95 : 5 - 70 : 30 weight ratio; and the carbon nanotube.
