Title:
PURIFICATION METHOD FOR GRAPHENE OXIDE
Document Type and Number:
WIPO Patent Application WO/2016/114617
Kind Code:
A1
Abstract:
The present invention relates to a purification method for graphene oxide, the method comprising a step in which an aqueous graphene oxide solution, which has been produced by using an acid and a heavy metal oxidising agent, is subjected to phase separation by using an organic solvent, and relates to a method for purifying high-purity graphene oxide in a simple and efficient fashion.
