Problems solved by technology

Existing antibacterial agents generally only have a single disinfection effect, with few types of antibacterial agents and narrow application areas
The speed of action is mostly slow, easy to be absorbed by the body, and has different degrees of side effects
And because of the formula of antibacterial agents, some antibacterial agents are slightly toxic, which is not conducive to health after being absorbed by the human body.
Moreover, the existing antibacterial agent also has the shortcoming of short effective period and slow response

Abstract

The invention discloses an antibacterial agent containing nanoscale graphene. The antibacterial agent contains nanoscale graphene, chlorhexidine iodine, polyethylene glycol, dimethylcarbinol, diacetyl tartaric acid ester of monoglyceride, distilled monoglyceride, glutaraldehyde, polypropylene glycol and carbamide. A method for preparing the antibacterial agent containing nanoscale graphene comprises the steps of 1, making nanoscale graphene and chlorhexidine iodine dissolved in distilled water, and continuing to add polyethylene glycol and dimethylcarbinol, so that a mixed solution A is obtained; 2, continuing to add diacetyl tartaric acid ester of monoglycerides, distilled monoglyceride, glutaraldehyde, polypropylene glycol and carbamide to the mixed solution A, continuing to conduct stirring for 0.5 h, and then transferring obtained solution into a reaction vessel for reaction, so that a mixed solution B is obtained; 3, conducting dehydration washing on the mixed solution B obtained in step 2 in a spin dryer with distilled water, and then conducting precipitation; and 4, conducting vacuum drying on precipitate obtained in step 3 in a drying oven. The antibacterial agent containing nanoscale graphene can be used for various kinds of disinfection clinically, and is suitable for disinfection of burns, scalds and wounds.

Description

technical field [0001] The invention relates to the field of antibacterial agents, in particular to an antibacterial agent containing nanoscale graphene and a preparation method thereof. Background technique [0002] For a long time, bacteria have been one of the culprits causing many diseases. In order to kill bacteria, antibiotics are widely used. Although they have achieved certain effects, their extensive use, especially abuse, can easily lead to bacterial mutation and drug resistance, resulting in more and more drug-resistant bacteria. Therefore, researchers are committed to finding other ways to eliminate bacteria. "In an experiment, we accidentally found that bacteria grow very slowly in places with graphene." Luo Yang, director of the Comprehensive Experimental Research Center, said. After consulting literature, Luo Yang's team found that there are only dozens of international reports on graphene's antibacterial properties, because the size of graphene, surface grou...
