NOVELTY - Graphene-nicotinic acid silver plating solution comprises 30-50 pts. wt. silver salt, 80-100 pts. wt. complexing agent, 60-70 pts. wt. buffer, 60-70 pts. wt. conductive salt, 30-50 pts. wt. additives, 0.3-0.5 pts. wt. graphene and 700-1100 pts. wt. water. USE - Graphene-nicotinic acid silver plating solution. ADVANTAGE - The graphene-nicotinic acid silver plating solution is rational in composition, stable in component, capable of uniformly dispersing the graphene, and has good popularization and application value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene-nicotinic acid silver plating solution, which involves: a. dissolving silver salt, complexing agent, buffer, conductive salt and additives in water to obtain electroplating solution; b. adding ammonia water to electroplating solution to adjust pH to 9.5-10.5 to obtain silver plating solution a; c. taking 30-50% of total amount of silver plating solution a, adding graphene powder particles, stirring uniformly, adding dispersant, ultrasonically treating for 15-30 minutes, adding remaining silver plating solution a, stirring uniformly, and ultrasonically treating again 15-30 minutes.
