Rapid Production of Metal Organic Framework - Fabrics for Air Filtration

疫情爆发一年半后，显然，个人和个人佩戴口罩 公共卫生问题是一个持续的问题，像三角洲的到来和蔓延这样的事件 和SARS CoV-2的Omicron变种。尽管众所周知，N95口罩是 作为防护的黄金标准，公众仍然压倒性地更喜欢布质口罩，因为 N95口罩的不适感觉和缺乏可重用性，以及呼吸的舒适性 布质面具的一部分。ASTM International最近发布了ASTM F3502-21标准， 为既不是医学上的也不是医疗上的“屏障面罩”的功效制定了指南 口罩也不是口罩，主要是针对布质口罩。然而，有非常多的 几个基于织物的面具(没有额外的插入滤镜)通过了这一标准，而没有 可洗涤和可重复使用的。 我们公司Hava Technologies的目标是创造一种具有 传统布制口罩的优点，如透气性和耐洗性，同时仍通过 ASTM-F3502过滤效能标准。为了做到这一点，我们利用了一种名为 金属有机骨架(MOF)。基于静电的MOF过滤研究表明 过滤效率接近并符合ASTM F3502 1级标准。更多 有趣的是，这些MOF面料经过25次洗涤后显示出有效的过滤效果，显示出 这些基于MOF织物的口罩和过滤器能够真正洗涤和重复使用 月份。该提案将侧重于以下具体目标： 1.创建统一的ASTM F3502一级标准的MOF-Fabric，确保安全 在使用过程中。 2.可水洗的MOF-模拟家庭使用条件的织物，包括热水和洗涤剂。 3.采用标准卷对卷涂布工艺大面积生产MOF织物， 包括一项关于对戴口罩的态度的公共卫生调查。 HAVA MOF涂层织物口罩的佩戴者将受益于呼吸具有显著 过滤效率比未涂布口罩更高。期待受到保护是合理的 具有更高亚微米过滤能力的口罩将减少 SARS CoV-2并随后降低新冠肺炎的发病率及其相关发病率， 死亡率和不利的经济影响。根据最近的一份市场研究报告， 全球口罩市场预计在2020年(Research Drive 2020)超过12亿美元，显示出 为公司制定了可行的商业化战略。

A year and a half later after the pandemic, it is evident that wearing masks for personal and public health concerns is an ongoing matter, with events like the arrival and spread of the Delta and Omicron variants of SARS CoV-2. Although it is well known that the N95 masks are the “golden standard” for protection, the public still overwhelmingly prefers cloth-based masks, due to the uncomfortable feeling and lack of reusability of the N95 mask, and the ease of breathing of the cloth-based masks. ASTM International recently published the ASTM F3502-21 standard, which creates guidelines for the efficacy of “Barrier Face Coverings” that are neither medical masks nor respirators and are primarily directed towards cloth masks. However, there are very few masks that are fabric-based (without extra insert filters) that pass this standard, and none that are washable and reusable. The goal of our company, Hava Technologies, is to create a cloth mask that has the benefits of a traditional cloth mask, such as breathability and washability, while still passing the ASTM-F3502 standard for filtration efficacy. To do this, we utilize a novel technology called metal-organic frameworks (MOFs). The electrostatic-based filtration of MOFs has shown filtration efficacy approaching and matching the ASTM F3502 Level 1 standard. More interestingly, these MOF-fabrics show effective filtration after 25 wash cycles, showing the capability of these MOF-fabric based masks and filters to be truly washable and reusable for months. The proposal will focus on the following specific aims: 1. Creation of MOF-fabric with uniform ASTM F3502 Level 1 standard and ensuring safety during usage. 2. Washable MOF-fabrics simulating home use conditions, including hot water and detergents. 3. Large area production of MOF-fabrics using standard roll-to-roll coating processing, including a public health survey of attitudes towards mask wearing. Wearers of Hava MOF-coated fabric masks will benefit by breathing air with significantly higher filtration efficiency than uncoated cloth masks. It is reasonable to expect protective masks with increased efficiency in sub-micron filtering capability would reduce transmission of SARS CoV-2 and subsequently reduce COVID-19 incidence with its associated morbidity, mortality, and adverse economic impact. According to a recent market research report, the global mask market is expected to surpass $1.2B in 2020 (Research Drive 2020), showing a viable commercialization strategy for the company.
