▎ 摘　　要

NOVELTY - Method for preparing graphene-based polymer, involves (a) preparing double-bonded graphene oxide, dissolving monomer in 100 pts. wt. ethanol comprising 1 pt. wt. prepared double-bonded graphene oxide, 30 pts. wt. methyl methacrylate, 20 pts. wt. acrylamide, 50 pts. wt. 3-acrylamidophenylboronic acid and 1-2 pts. wt. azobisisobutyronitrile, and heating the dissolved solution at 80 degrees C for 30 minutes to obtain the graphene-based polymer. USE - The method is useful for preparing graphene-based polymer. ADVANTAGE - The method effectively test glucose in two different physiological environments of blood sugar and saliva, improves the interference of proteins in the glucose detection process and accuracy of identifying the glucose concentration. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a crystal oscillator, involving (i) preparing the graphene-based polymer by the above-mentioned method, dispersing the prepared graphene-based polymer in ethanol to obtain a graphene-based polymer dispersion solvent, and (ii) spin-coating the graphene-based polymer dispersion solvent on crystal plate, and evaporating the graphene-based polymer dispersion solvent at room temperature.
