Beschreibung
Zusammenfassung:	The present invention relates to a polymer composite material into which a graphene oxide/carbon nanotube composite is introduced and a method for preparing the same. The method for preparing a polymer composite material into which the graphene oxide/carbon nanotube composite is introduced comprises: (1) preparing a dispersed solution containing graphene oxide and carbon nanotubes; (2) mixing the dispersion solution in a biodegradable polymer solution; (3) pouring the mixed solution prepared through step (2) onto a substrate and evaporating a solvent. According to the present invention, graphene oxide and carbon nanotubes may be stably dispersed by using the structural properties of graphene oxide and carbon nanotubes, thereby obtaining an effect of providing a polymer composite material having improved mechanical properties. 본 발명은 그래핀 산화물/탄소나노튜브 복합체가 도입된 고분자 복합재료 및 그 제조방법에 관한 것이다. 상기 그래핀 산화물/탄소나노튜브 복합체가 도입된 고분자복합재료의 제조방법은 (1) 그래핀 산화물 및 탄소나노튜브를 포함하는 분산용액을 제조하는 단계; (2) 생분해성 고분자 용액에 상기 분산용액을 혼합하는 단계; (3) 상기 (2)단계를 거쳐 제조된 혼합용액을 기판에 부은 후 용매를 증발시키는 단계를 포함한다. 본 발명에 따르면 그래핀 산화물 및 탄소나노튜브의 구조적 성질을 이용해 그래핀 산화물과 탄소나노튜브를 안정하게 분산시킴으로써 기계적 특성이 향상된 고분자 복합소재를 제공하는 효과가 있다.
