Zusammenfassung:	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. 본 발명은 탄소나노튜브-스테레오 콤플렉스 폴리락트산 복합재료에 관한 것으로, 폴리락트산 스테레오 콤플레스 결정을 이용하여 탄소나노튜브의 연결성(conectivity)을 향상시켜 전도성 물성을 향상시킨 복합재료인 것이다. 본 발명에 따른 복합재료는 소량의 탄소나노튜브로 극대화된 전기전도도 효율을 얻을 수 있어 전도성이 필요한 소재에 다양하게 활용될 수 있다.
