As the COVID-19 pandemic continues, the importance of sterilization eliminating bacteria and viruses becomes even more emphasized. There are growing public concerns of pathogen transmission via commonly touched surfaces such as transit handlebars, elevator buttons, door handles, the touchpad of bank ATMs, etc. Even though there are many sanitizers available, it is quite tedious since it must be rubbed and applied by hand frequently. There is an urgent need to have antimicrobial surface coatings with which the routine sanitization on such surfaces will no longer be required. In order to respond this urgent need, the University of Calgary and Flair Flexible Packaging Corp. have cooperated to develop copper nanocomposite coatings to kill bacteria and viruses. Flair's products are commonly seen in a variety of food packaging. Due to the current pandemic concerns, their customers are also very interested in the antimicrobial surfaces. The outcome of this research will minimize the lifespan of bacteria and viruses on the surface of the packages, thereby reducing the possibility of spreading pathogens via touching the packages. More importantly, the antimicrobial coating technologies will applicable to not only the product packages but also the surface of public areas such as clinics, nursing homes, or hospitals where there is a higher risk of COVID-19 infection. The new copper nanocomposite coating will be designed and developed by the optimized condition of copper nanoparticles, polymer, and solvent mixtures. The antibacterial and antiviral activity of the coating will be tested with different bacteria and viruses. The new development would provide an alternative way to respond to the ever-growing demands for antimicrobial coating with cost-effectiveness and time efficiency. The collaborative research will benefit Canada by providing health, economic, and environmental benefits as well as a way to facilitate the training of HQP with a variety of professional and technical skills.

随着共同-19大流行的继续，消除细菌和病毒的灭菌的重要性变得更加强调。通过常见触摸的表面，例如过境车把，电梯按钮，门把手，银行ATMS的触摸板等，人们对病原体传播的关注日益增加。尽管有许多消毒剂可用，但它仍然很乏味，因为它必须经常手动擦拭和涂抹。迫切需要使用抗菌表面涂层，不再需要在此类表面上进行常规消毒。 为了应对这种迫切的需求，卡尔加里大学和柔韧性包装公司已合作开发铜纳米复合涂料以杀死细菌和病毒。 Flair的产品通常在各种食品包装中看到。由于目前的大流行问题，他们的客户也对抗菌表面非常感兴趣。这项研究的结果将最大程度地减少包装表面上细菌和病毒的寿命，从而减少通过接触包装传播病原体的可能性。更重要的是，抗菌涂料技术不仅适用于产品包，而且适用于公共区域的表面，例如诊所，疗养院或医院，那里有更高的Covid-19感染风险。新的铜纳米复合涂层将通过铜纳米颗粒，聚合物和溶剂混合物的优化状态设计和开发。涂层的抗菌和抗病毒活性将通过不同的细菌和病毒进行测试。 新的开发将提供另一种方法，以响应成本效益和时间效率的抗菌涂层的不断增长的需求。合作研究将通过提供健康，经济和环境福利以及促进以各种专业和技术技能培训HQP来使加拿大受益。
