Abstract

The present invention discloses a functionalized graphene oxide supported nano-silver preparation method, and relates to a sterilization technique, wherein the functionalized graphene oxide supported nano-silver is preferably amino-modified polyethylene glycol functionalized graphene oxide supported nano-silver, and the modification component is amino-modified polyethylene glycol functionalized graphene oxide. Preferably the method comprises: preparing graphene oxide, preparing amino-modified polyethylene glycol modified graphene oxide, and finally preparing nano-silver respectively with particle sizes of 10 nm, 30 nm and 50 nm. According to the present invention, the functionalized graphene oxide supported nano-silver with different particle sizes are prepared and are used for the antibacterial field, and the particle size of the functionalized graphene oxide supported nano-silver having the optimal antibacterial effect is found through the antibacterial effect comparison.

Description

technical field [0001] The invention relates to a sterilization technology, in particular to a preparation method of functionalized graphene oxide-loaded nano-silver. Background technique [0002] Health is one of the topics that people are most concerned about. However, bacteria are everywhere and pervasive, and their spread and spread seriously threaten human health. Using antibacterial materials to kill and inhibit the growth and reproduction of harmful bacteria is an important means to improve human health. [0003] In response to the resistance of bacteria to antibiotics, it is an important strategy in the field of medicine to develop more efficient antibacterial drugs, especially drugs that inhibit drug-resistant bacteria. Among many antibacterial materials, inorganic antibacterial agents have the advantages of low toxicity and side effects on the human body and little environmental pollution, which have attracted people's attention. Inorganic antibacterial agents ma...
