摘要

目的:制备一种可涂覆于材料表面、具有抑菌抗病毒性能的涂膜,旨在应用于多种公共场所设施表面以控制病原微生物的传播.方法:以无毒易挥发的乙醇溶解聚乙烯醇缩丁醛(PVB)树脂材料,通过掺杂具有抑菌抗病毒性能的纳米氧化锌(ZnONP)或纳米氧化铜(CuONP)颗粒,制备具有抑菌抗病毒性能的涂膜材料,并研究纳米颗粒种类、粒径、掺杂量对涂膜消毒性能的影响.结果:扫描电镜表征结果表明CuONP和 ZnONP 可与 PVB形成稳定涂膜,且该涂膜的接触面积越大、纳米颗粒掺杂量越高,对大肠杆菌、MS2 噬菌体的灭活效果越好.接触面积大于80 cm2 时灭活率可达 90%,且去除速率大于 1%/min.结论:PVB复合涂膜具有高效的抑菌抗病毒活性,可为公共卫生消毒提供新手段.

Abstract

Objective:Coating films were fabricated with antibacterial and antiviral activity,which can be widely used on surfaces of public facilities to control the microbiological risk.Methods:The resin polyvinyl butyral(PVB)was dissolved in non-toxic and volatile ethanol,and then nano-zinc oxide(ZnONP)or nano-copper oxide(CuONP)particles with antibacterial and antiviral effects were added.The disinfection performance of the coating films was investigated via adding nanoparticles with different sizes and amounts.Results:Analyses of scanning electron microscopy showed that CuONP and ZnONP formed uniform films with PVB.In addition,the larger contact area and the higher dosage of nanoparticles promoted the bactericidal effect against E.coli and MS2 phage.With the contact area larger than 80 cm2,the removal can reach up to 90%with removal rate over 1%/min.Conclusion:The PVB composite coating films have high antibacterial and antiviral activity,which provides a new approach to control microbiological risk for public health.
