Beschreibung
Zusammenfassung:	The present invention relates to a graphene production method, a graphene dispersion composition, and a production method thereof. More specifically, provided is a graphene production method which comprises the following steps: producing a graphite intercalation compound by treating a mixture of natural graphite and alkali metal with heat; mixing the graphite intercalation compound along with a pyridine-based solvent; and treating the mixture of the graphite intercalation compound and the pyridine-based solvent with ultrasound. Moreover, provided are a graphene dispersion composition containing the same, and a production method thereof. 그래핀 제조방법, 그래핀 분산 조성물, 및 그 제조방법 에 관한 것으로, 천연 흑연 (Graphite), 및 알칼리 금속의 혼합물을 열처리하여 흑연층간화합물을 제조하는 단계; 상기 흑연층간화합물을 피리딘계 용매와 혼합하는 단계; 및 상기 혼합된 흑연층간화합물 및 피리딘계 용매를 초음파처리하는 단계;를 포함하는, 그래핀 제조방법, 이를 포함하는 그래핀 분산 조성물, 및 이의 제조방법을 제공할 수 있다.
