Title:
INDUSTRIAL CONTINUOUS PREPARATION EQUIPMENT AND PROCESS FOR GRAPHENE POWDER CAPABLE OF BEING DIRECTLY DISPERSED IN ORGANIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/207629
Kind Code:
A1
Abstract:
The present invention relates to the field of graphene preparation, and in particular to industrial continuous preparation equipment and process for graphene powder capable of being directly dispersed in an organic system, for use in obtaining the graphene powder capable of being directly dispersed in the organic system, which is composed of reduced graphene oxide and oil-soluble polymer micro-nano particles tightly coated on the reduced graphene oxide, wherein a part of the oil-soluble polymer micro-nano particles are, by means of a π-π conjugation effect, tightly combined with hexagonal honeycomb lattices formed by sp2 hybrid orbits in the reduced graphene oxide, and the other part of the oil-soluble polymer micro-nano particles are combined with oxygen-containing functional groups in the reduced graphene oxide by means of a covalent effect. On one hand, the surface of the reduced graphene oxide can be tightly coated with the oil-soluble polymer micro-nano particles, such that agglomeration of the reduced graphene oxide in a spray drying process is effectively prevented. On the other hand, the dried graphene powder can be easily dispersed after being transferred into the organic system, and the dispersion stability can be kept for a long time.
