Facemasks play an essential role in protecting the public from the risks of COVID-19 transmission. Unfortunately, facemasks are either ineffective or complex and expensive items that are only suitable for use in a hospital. There is limited evidence that they are effective for use by the general public, despite the obvious potential to reduce transmission rates if effective. A key reason that current consumer facemasks are ineffective is their inability in activate viruses and prevent the build-up of liquid droplets in the fabric - which is primarily due to the current materials of construction.The aim of this project is to demonstrate the effectiveness of a two-sided coating for fabrics that can enable design of simple, low-cost, single layer facemasks that reduces the transmission of viruses such as COVID-19\.The coatings we have identified are designed to provide water-resistance and anti-viral functionalities to a single fabric; enabling low-cost single-layer facemasks to be produced at scale. There are currently no alternative technologies that are able to deliver convenient single-pass two-sided coating of fabrics. The global demand is expected to be high and rapidly growing, with an urgent need for at least 20 million masks per day to address the current COVID-19 pandemic .We have successfully demonstrated the deposition of antiviral/water-resistant functionalities on various fabrics for facemasks and this has been proven effective against pathogenic bacteria and viruses. This “extension for impact” will be used to demonstrate the potential of our coating technology to deliver antiviral functionality to fabrics for medical products and sportswear. These two important product categories are used in environments where the risk for viral transmission are high and antiviral coatings can play a key role in reducing the spread of pathogenic species, such as the SARS-CoV-2 virus, which causes Covid-19. Furthermore, this project extension significantly increases the addressable market for our Novara technology and increases the commercial potential of the project.

口罩在保护公众免受 COVID-19 传播风险方面发挥着重要作用，但遗憾的是，口罩要么无效，要么复杂且昂贵，仅适合在医院使用。尽管如果有效的话，明显有可能降低传播率，但目前的消费型口罩无效的一个关键原因是它们无法激活病毒并防止液​​滴在织物中积聚，这主要是由于目前的情况。建筑材料。目的该项目的目的是展示织物双面涂层的有效性，该织物可以设计简单、低成本的单层口罩，从而减少 COVID-19 等病毒的传播。我们已确定的涂层经过设计为单一织物提供防水和抗病毒功能；实现低成本单层口罩的大规模生产。目前还没有替代技术能够提供方便的单程双面涂层。全球需求是预计将保持高位且快速增长，每天迫切需要至少 2000 万个口罩来应对当前的 COVID-19 大流行。我们已成功演示了在各种口罩织物上沉积抗病毒/防水功能，这已经已被证明对致病细菌和病毒有效。这种“影响延伸”将用于证明我们的涂层技术为医疗产品和运动服的织物提供抗病毒功能的潜力，这两个重要的产品类别在使用的环境中。风险病毒传播率很高，抗病毒涂层可以在减少致病物种（例如导致 Covid-19 的 SARS-CoV-2 病毒）的传播方面发挥关键作用。此外，该项目扩展显着增加了我们 Novara 技术的潜在市场。并增加项目的商业潜力。
