Abstract

The invention discloses a preparation method and application of a ternary composite antibacterial film material of rGO-MoS2-Fe2O3. Reduced graphene oxide (rGO), molybdenum disulfide (MoS2) and C10H12FeN2NaO8 are used as raw materials, a simple one-pot method is adopted for preparing the ternary composite antibacterial material of rGO-MoS2-Fe2O3, the ternary composite antibacterial material of rGO-MoS2-Fe2O3 presents a typical layered structure of a two-dimensional material, iron particles are successfully loaded and uniformly distributed, and good inhibition effects are achieved on staphylococcus aureus and escherichia coli. The prepared rGO-MoS2-Fe2O3 ternary antibacterial compound is added into CMC as a nano-filler, and a CMC / rGO-MoS2-Fe2O3 composite film is prepared by adopting a solution tape casting method, so that the mechanical property of the CMC biopolymer film is improved, the light transmittance of the CMC biopolymer film is improved, the CMC biopolymer film is endowed withstronger antibacterial activity, and the CMC / rGO-MoS2-Fe2O3 ternary antibacterial composite film has potential application in the field of antibacterial food packaging materials.

Description

technical field [0001] The invention relates to the technical field of preparation of antibacterial materials, in particular to a rGO-MoS 2 -Fe 2 o 3 The preparation method and application of the ternary composite nano antibacterial film material. Background technique [0002] With the development of society, people pay more and more attention to the safety and health requirements of food, medicine and medical equipment. The abuse of antibiotics leads to the emergence of drug-resistant bacteria, which causes the human body to produce immunosuppression and reduce the resistance to diseases. As a new type of functional material, antibacterial materials have good antibacterial and bactericidal properties, which help to avoid the emergence of drug-resistant bacteria and protect public health. Graphene and molybdenum disulfide have shown great development potential in the field of antibacterial materials due to their unique structural properties and their own oxidative stress...
