Title (EN) METHOD FOR PREPARING GRAPHENE BY USING HIGH SPEED HOMOGENIZATION PRETREATMENT AND HIGH PRESSURE HOMOGENIZATION
(FR) PROCÉDÉ DE PRÉPARATION DE GRAPHÈNE À L'AIDE D'UN PRÉTRAITEMENT PAR HOMOGÉNÉISATION À UNE VITESSE ÉLEVÉE ET D'UNE HOMOGÉNÉISATION À HAUTE PRESSION
(KO) 고속 균질화 전처리 및 고압 균질화를 이용한 그래핀의 제조 방법
Abstract: front page image
(EN)The present invention relates to a method for preparing graphene, the method preparing a feed solution by high-speed homogenizing expanded graphite, and then high-pressure homogenizing the same, thereby improving the efficiency of high pressure homogenization by increasing the dispersity of expanded graphite in the feed solution. Therefore, compared with a conventional process, the efficiency of graphene preparation is excellent and the size of graphene to be prepared is uniform.
(FR)La présente invention concerne un procédé de préparation de graphène, le procédé consistant à préparer une solution d'alimentation par homogénéisation à une vitesse élevée de graphite expansé, et ensuite à homogénéiser celle-ci à haute pression, ce qui permet d'améliorer l'efficacité d'une homogénéisation à haute pression en augmentant la dispersibilité du graphite expansé dans la solution d'alimentation. Par conséquent, par comparaison avec un procédé classique, l'efficacité de préparation de graphène est excellente et la taille du graphène ainsi préparé est uniforme.
(KO)본 발명은 그래핀 제조 방법에 관한 것으로, 팽창 그라파이트를 고속 균질화화여 피드 용액을 제조한 다음 이를 고압 균질화함으로써, 피드 용액 내 팽창 그라파이트의 분산도를 높여 고압 균질화의 효율을 높일 수 있다. 이에 따라 기존 공정에 비하여 그래핀의 제조 효율이 우수하고, 제조되는 그래핀의 크기가 균일하다는 특징이 있다.
