Embodiment 1
[0046] According to one embodiment of the present invention, a kind of preparation method of graphene-based polymer comprises:
[0047] Preparation of double bonded graphene oxide.
[0048] Dissolve the monomer in 1000 parts of N,N'-dimethylformamide according to the following ratio:
[0049] 1 part graphene oxide, 1 part chloropropene, 1 part potassium hydroxide.
[0050] The dissolved solution was heated to 60° C. for 24 hours to react, centrifuged, washed, and dried to obtain double-bonded graphene oxide.
[0051] In this example, 1000 parts of N,N'-dimethylformamide is based on 50mL, then the corresponding 1 part of graphene oxide is selected as 50mg, the corresponding 1 part of chloropropene is selected as 50uL, and the corresponding potassium hydroxide is selected as 50mg (0.05g).
[0052] Disperse 50mg of graphene oxide, 50uL of chloropropene, and 50mg of potassium hydroxide in 50mL of N,N'-dimethylformamide for dissolution.
[0053] After the dissolved solution was...

The invention provides a graphene-based polymer preparation method and a quartz crystal oscillator preparation method. The graphene-based polymer preparation method comprises the following steps: preparing double-bonded graphene oxide; dissolving the following monomers in parts into 100 parts of ethanol: 1 part of the prepared double-bonded graphene oxide, 30 parts of methyl methacrylate, 20 partsof acrylamide, 50 parts of 3-acrylamide phenylboronic acid and 1-2 parts of azodiisobutyronitrile; heating the solution obtained after dissolution to 80 DEG C to implement a reaction for 30 minutes so as to obtain a graphene polymer; dispersing the prepared graphene polymer into ethanol so as to obtain a graphene polymer dispersion solvent; and spinning the graphene polymer dispersion solvent toa crystal oscillator, and evaporating off the graphene polymer dispersion solvent at the room temperature. By adopting the graphene-based polymer preparation method, two glucoses of different physiological environments, namely blood glucose and salivary sugar, can be effectively tested simultaneously, in addition, protein inference in the glucose detection process can be greatly improved, and accuracy in glucose concentration recognition can be improved.
Description
technical field [0001] The invention relates to the technical field of nanometer materials, in particular to a preparation method of a graphene-based polymer and a preparation method of a quartz crystal oscillator. Background technique [0002] Diabetes is a group of metabolic diseases characterized by hyperglycemia. Hyperglycemia is caused by defective insulin secretion or impaired biological action, or both. The long-term high blood sugar in diabetes leads to chronic damage and dysfunction of various tissues, especially the eyes, kidneys, heart, blood vessels, and nerves. Diabetes cannot be cured, and patients need to monitor the concentration of glucose in the blood for life, and give necessary treatment plans according to the concentration of blood glucose. In order to meet the diagnosis and treatment needs of diabetic patients and improve the quality of life of patients, effective and easy-to-accept detection methods and technologies have become a research hotspot tha...
