▎ 摘　　要

NOVELTY - The method involves preparing graphite vinyl stannic oxide using a graphene nano sheet. A three-dimensional tin dioxide gas gel is obtained. Graphene oxide dimethyl formamide solution is added with small amount of concentrated hydrochloric acid. Metal chloride is added and mixed to the graphene oxide dimethyl formamide solution at temperature of 60-90 degrees Celsius for 12 hours. Reacted solution is added with de-ionized water to obtain concentrated deionized water dispersion liquid. USE - Graphene tin dioxide composite material preparation method. ADVANTAGE - The method enables improving stability and performance of a graphite vinyl stannic oxide composite material, and increasing tin dioxide material discharging capacity. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical illustration of a graphene tin dioxide composite material preparation method.'(Drawing includes non-English language text)'
