Title:
METHOD FOR PREPARING GRAPHENE BY USING HIGH SPEED HOMOGENIZATION PRETREATMENT AND HIGH PRESSURE HOMOGENIZATION
Document Type and Number:
WIPO Patent Application WO/2016/093645
Kind Code:
A8
Abstract:
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.
