The ongoing COVID-19 pandemic has pushed scientists and technologists to find novel strategies to develop new materials to prevent the transmission, spread, and entry of pathogens into the human body. In this report, the fabrication of polyvinyl chloride (PVC)-SiO₂-Ag composite is presented, in which the percentage of Ag is 0.84% wt. Our findings render that this composite eliminates (> 99.8%) bacteria and fungus (Staphylococcus aureus, Escherichia coli, Penicillium funiculosum) and SARS-CoV-2, by surface contact in 2 h hours and 15 min, respectively. Specific migration analysis shown that the use of the PVC-SiO₂-Ag composite is considered safe and effective for food preservation. This research and innovation front can be considered a breakthrough for the design of biocide materials. Future directions for this exciting and highly significant research field can open the door to the development of new technologies for the fabrication of packaging films to protect consumer products (such as fruits, vegetables, and other foods).

持续的 COVID-19 大流行促使科学家和技术人员寻找新策略来开发新材料，以防止病原体传播、传播和进入人体。在本报告中，提出了聚氯乙烯 (PVC)-SiO ₂ -Ag 复合材料的制造，其中 Ag 的百分比为 0.84% wt。我们的研究结果表明，该复合材料通过表面接触分别在 2 小时和 15 分钟内消除（> 99.8%）细菌和真菌（金黄色葡萄球菌、大肠杆菌、绳索青霉）和 SARS-CoV-2。具体迁移分析表明，使用PVC-SiO ₂-Ag 复合物被认为对食品保鲜是安全有效的。这一研究和创新前沿可以被认为是杀菌剂材料设计的一个突破。这一激动人心且意义重大的研究领域的未来方向可以为开发用于保护消费品（如水果、蔬菜和其他食品）的包装膜制造新技术打开大门。
