技术领域Technical field
本申请涉及功能薄膜技术领域，尤其涉及一种抗病毒抗菌功能薄膜及其制备方法。This application relates to the technical field of functional films, in particular to an antiviral and antibacterial functional film and a preparation method thereof.
背景技术Background technique
近年来，新型流感、新型冠状、埃博拉等各种病毒、肺炎克雷伯菌等细菌所致的感染症已威胁到人类的生命，特别是近十几年爆发的几次由病毒传播感染引起的大规模疫情，造成全世界大量的人员伤亡和经济损失，因此在世界范围内急需寻找应对策略。In recent years, infections caused by various viruses such as the new influenza, new coronavirus, Ebola, Klebsiella pneumoniae and other bacteria have threatened human life, especially the outbreaks of several virus-transmitted infections in the past ten years. The large-scale epidemic caused by it has caused a large number of casualties and economic losses all over the world. Therefore, it is urgent to find a response strategy worldwide.
使用次氯酸、过氧化氢等化学杀菌试剂能够消灭细菌、病毒等微生物的病原体，但抗菌效果持续性低、无法达到长效抗菌，从而不能有效防止接触传染。因此，对具有长效抗菌抗病毒功效的功能膜材料的需求提高。CN105348756B公开了一种抗菌聚酯薄膜及其制备方法与它的用途，将纳米银分散在聚酯切片中制备抗菌性薄膜制品，其对大肠杆菌和金黄色葡萄球菌的抗菌率≥99％。虽然上述薄膜具有良好的抗菌性，但也存在着纳米银材料在聚酯切片中分散性低，抗菌性不均的问题，且制备工艺复杂、应用不方便。The use of chemical germicidal agents such as hypochlorous acid and hydrogen peroxide can eliminate the pathogens of bacteria, viruses and other microorganisms, but the antibacterial effect is low and can not achieve long-term antibacterial, so it cannot effectively prevent contact and infection. Therefore, the demand for functional film materials with long-lasting antibacterial and antiviral effects has increased. CN105348756B discloses an antibacterial polyester film and its preparation method and its use. Nano silver is dispersed in polyester chips to prepare antibacterial film products, and its antibacterial rate against Escherichia coli and Staphylococcus aureus is ≥99%. Although the above-mentioned film has good antibacterial properties, it also has the problems of low dispersion of nano-silver materials in polyester chips, uneven antibacterial properties, complicated preparation processes and inconvenient application.
