The invention discloses a thiol-modified graphene oxide and a preparation method thereof. The mercapto-modified graphene oxide is a modified graphene oxide product obtained by introducing mercapto groups into the graphene oxide sheet structure. The preparation method is: after mixing graphene oxide solution, solvent and triethylamine evenly, add thiocarboxylic acid or thiocarboxylate under nitrogen protection; react at 10-70 degrees Celsius for 1-7 days to obtain thioester Modified latent sulfur graphene oxide; the thioester modified latent sulfur graphene is centrifugally washed with deionized water to obtain thiol-modified graphene oxide; or the thioester modified latent sulfur graphene is mixed with dilute After the hydrochloric acid is mixed evenly, it is centrifuged and washed with deionized water to obtain mercapto-modified graphene oxide. The preparation process of the present invention is simple, safe and controllable, less time-consuming and energy-consuming, and the mercapto-modified graphene oxide is prepared, which further broadens the synthesis means and application fields of graphene-derived materials and sulfur-containing compounds.

The invention discloses a graphene-silver composite fiber and a preparation method thereof. The method comprises the steps of firstly preparing a graphene oxide fiber of which the diameter is 1-50 microns by adopting a wet spinning method, and then putting the graphene oxide fiber into a high-temperature furnace for heating and reducing to obtain a continuous pure graphene fiber. Due to a special treatment mode, the fiber surface is provided with multi-stage wrinkles, the pure graphene fiber is fixed on a negative electrode of a plating bath for electroplating, and a copper layer has an extension structure embedded into the wrinkles. Graphene is tightly combined with silver crystals, a hole defect is avoided, the electrical properties of the material are greatly improved, and the fiber is stable in structure and constant in electric conductivity after being bent for 100 times.

The invention discloses a pollution-free low-cost technology for preparing graphene oxide. The technology comprises the following steps: 1, mixing graphite with a strong acid to infiltrate graphite, adding a strong oxidant, and continuously stirring to oxidize and exfoliate graphite layers; 2, centrifuging the obtained reaction solution, recovering the strong acid to be used in a next reaction, slowly pouring the obtained muddy product into deionized water, stirring, washing by using dilute hydrochloric acid, repeatedly cleaning by using deionized water, and centrifuging to obtain monolayer graphene oxide; 3, introducing ammonia gas into wastewater until the pH value approaches 7 to obtain an inorganic fertilizer containing nitrogen, potassium, iron and phosphorus; and 4, concentrating an aqueous solution of graphene oxide, and drying to obtain graphene oxide with high density and high specific surface area. The technology has the advantages of simple, safe and controllable preparation process, less time and energy consumption, no explosion danger and no pollution. The cycle use of concentrated sulfuric acid in the raw material-to-fertilizer process makes all raw materials and elements fully used, so the preparation cost of graphene oxide is greatly reduced.

The present invention firstly finds that the clutch with a clutch ring is overheated due to continuous use of the electromagnetic coil, which is the main reason for the failure of the clutch. And for this purpose, a clutch reliability improvement system is proposed, the system can adjust the loaded pull-in voltage, and ensure the reliability of the clutch pull-in by ensuring the redundant value of the lifting force of the electromagnet to the clutch ring.

The invention discloses a brewing method of kiwi-flavored sweet corn wine. The brewing method comprises the steps as follows: selecting fresh brewing sweet corn ears which are pollinated 25 days before, adding water, homogenizing to obtain sweet corn juice, and cleaning and homogenizing green kiwi fruit to obtain kiwi raw juice; mixing 75-85% of brewing sweet corn juice with 25-15% of pea juice to obtain a distiller's yeast culture medium, inoculating with yeast subjected to slant culture, and carrying out progressive amplification culture in distiller's yeast seeding tanks to obtain liquid distiller's yeast; adding the kiwi raw juice, the brewing sweet corn juice and the liquid distiller's yeast into a fermentation tank, fermenting at 15-20 DEG C for 21-14 days, harrowing and supplementing white granulated sugar with a ratio of 8.5-17% on the 7th -10th day of fermentation, filtering, and carrying out microwave treatment on the filtrate to obtain kiwi-flavored sweet corn wine base; pumping the kiwi-flavored sweet corn wine base into an aging tank to be stored at 16 DEG C below for more than 18 months; and adding sweet corn Brandy of which the amount accounts for 3-5% the weight ofthe aged sweet corn wine to obtain the kiwi-flavored sweet corn wine. The obtained kiwi-flavored sweet corn wine has kiwi fruit aroma and rice wine mellowness, is moderate in alcohol degree, mellow, elegant and nutrient, and satisfies the fashion of health-care driving.
