▎ 摘　　要

NOVELTY - Preparing graphene mother liquor comprises e.g. (i) dispersing 30-50 pts. wt. graphene in aqueous solution of sodium polyphosphate, sonicating, then adding 40-60 pts. wt. acidified modified nano bentonite, taking graphene and nano-bentonite as carrier, stable, uniform load in nano-bentonite, filtering, washing and drying to obtain graphene-bentonite complex, and (ii) mixing graphene-bentonite complex and 100-200 pts. wt. organic solvent, then adding 20-30 pts. wt. phenol into mixed system, stirring, and then adding 1-3 pts. wt. surfactant, and dispersing by magnetic stirring. USE - The graphene mother liquor is useful in thermosetting phenolic resin (claimed). ADVANTAGE - The method is simple, has short reaction condition, low cost, and is suitable for industrial production. DETAILED DESCRIPTION - Preparing graphene mother liquor comprises (i) dispersing 30-50 pts. wt. graphene in aqueous solution of sodium polyphosphate, sonicating, then adding 40-60 pts. wt. acidified modified nano bentonite, sodium polyphosphate carrying graphene and acidified modified nano-bentonite affinity between acidified nano-bentonite sheet, chip surface complex to form complex, taking graphene and nano-bentonite as carrier, stable, uniform load in nano-bentonite, filtering, washing and drying to obtain graphene-bentonite complex, and (ii) mixing graphene-bentonite complex and 100-200 pts. wt. organic solvent, then adding 20-30 pts. wt. phenol into mixed system, stirring, and then adding 1-3 pts. wt. surfactant, and dispersing by magnetic stirring. An INDEPENDENT CLAIM is also included for graphene mother liquor obtained by above method.
