NOVELTY - Ternary nano antibacterial film material, which uses carboxymethyl cellulose (CMC) as substrate and adding the prepared reductive graphene oxide-molybdenum disulfide-ferric oxide (rGO-MoS2-Fe2O3) ternary antibacterial compound to carboxymethylcellulose (CMC) as nano filler. USE - The material is useful in preventing pathogenic bacteria, preferably Escherichia coli and Staphylococcus aureus (claimed). ADVANTAGE - The material: is prepared by a simple one-pot method, which presents a typical layered structure of a two-dimensional material; successfully loads and evenly distributes iron particles; improves the mechanical properties of the CMC biopolymer film and light transmittance and gives strong antibacterial activity.
