二维抗菌材料研究进展及其在皮革涂饰中的应用展望

A Review on the Research Progress of Two-Dimensional Antibacterial Materials and their Potential Application in Leather Finishing

细菌侵蚀会影响革制品使用性能,也会对消费者健康产生一定的危害。虽然添加抗菌剂可有效减少这一问题的发生,但传统抗菌剂作用靶标单一且通常位于细菌内,细菌易通过多种机制产生耐药性。二维抗菌材料(如氧化石墨烯、二硫化钼、二维过渡金属碳/氮化物、黑磷、氮化碳等)具有物理破膜、物理包裹、氧化应激等多种抗菌机制,可有效避免细菌产生耐药性。文章总结了国内外二维抗菌材料的主要研究进展,并对这类新型抗菌材料在皮革涂饰领域的应用进行了展望。

Bacterial erosion can not only affect the performance of leather goods,but also do harm to the health of consumers.Adding antibacterial agents is an effective strategy to reduce the occurrence of this problem.However,traditional antibacterial agents usually have single target that locates inside bacteria.In this case,bacteria could acquire drug-resistance through multiple mechanisms.The emerging two-dimensional materials(e.g.graphene oxide,molybdenum disulfide,two-dimensional transition metal carbon/nitride,black phosphorus,carbon nitride,etc.)have synergistic antibacterial mechanisms,such as physical destruction of cell membrane,physical wrapping,and oxidative stress,which hold the potency for inhibiting the occurrence of drug-resistance.This paper summarized the current research progress on the two-dimensional antibacterial materials worldwide,and prospected the application of such new antibacterial materials in leather finishing.
