▎ 摘　　要

NOVELTY - The paper has a substrate and a thin film structure provided with graphene sheets formed by a stacking and a contact electrode. A film structure of the graphene sheets is formed by stacking tightly combined with the substrate. The contact electrode is connected with a graphene sheets thin film structure. The graphene sheets film structure on the graphene sheet is attached with an auxiliary film forming agent and chemical sniffer molecule. Thickness of a film structure is formed by stacking of the graphene sheets is about 5 to 1000 microns. USE - Graphene test paper. ADVANTAGE - The paper can analyze quantity of organic solvent, salt solution, various drinks and other liquids, detect instrument, has little sample demand, and is inexpensive, reagent manufacturing time is short. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) preparation method for graphene test paper (2) liquid analyzing method for graphene test paper. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene test paper.
