我们目前的P42项目(项目5)涉及用于目标过滤的天然和回收纤维材料 土壤修复的方向。这项补充资金申请(针对项目5)直接满足了 新冠肺炎大流行，以天然纤维为基本主题的个人防护过滤介质。 新冠肺炎大流行的快速传播不仅使P42社区面临的风险成倍增加 来自土壤/空气的颗粒物和重金属污染，但现在增加了病毒的风险。 为社区提供低成本、可重复使用和可生物降解的个人防护设备(PPE)解决方案 将具有巨大的价值。最需要的物品之一是个人防护口罩，不仅仅是医疗保健提供者的 而是广大的公众。所有化妆和配置的口罩的使用都在不断增加，而且它们的使用也在继续 成倍增长。各种联邦简报都强调了为每个人戴口罩的必要性， 全世界每天可以戴超过5亿个口罩。数以亿计的N95口罩已经面世 在全球范围内生产和使用。大多数情况下，这些垃圾在一次性使用后被丢弃(最多2-3次) 这将导致垃圾填埋场的数量巨大。这将导致巨大的有害环境影响。 在未来的几年里。在这个项目中，我们提出了创新而实用的科学来开发天然纤维(基于生物的)。 符合NIOSH N95过滤效率(FE)标准的可生物降解过滤材料。基于生物的 解决方案是基于亚微米再生纤维素天然纤维(RNCF)和少量纺织级 碳纤维(TCF)，将设计用于涡轮充电，提供相互作用，以捕获和杀死 病毒。基于RNCF的过滤材料将同样有效地替代(或补充)合成的 基于聚丙烯(PP)的直径为2微米、每平方米50克(GSM)的过滤材料(不可生物降解) 目前在N95口罩中使用。这项工作将为产品解决方案提供一个切实的完整概念，以便实施 该团队已经在开发可重复使用的RNCF材料。整个解决方案将是 环保、安全，符合NIOSH标准。该项目开发的材料将是 针对NIOSH 42 CFR 84进行了测试，对固体和液体气溶胶的最低过滤效率为95% 不含油的。该产品将被传播到P42生态系统，包括医疗保健提供者 以及整个社区。这些小组的反馈将以调查、问卷、 培训和数据将进行统计分析，并成为主要P42赠款的一部分。该项目是 田纳西大学(UT)、橡树岭国家实验室(ORNL)、田纳西大学 阿拉巴马州伯明翰和P42社区。

Our current P42 project (Project 5) deals with natural and recycled fiber materials for filtration targeted toward soil remediation. This supplemental funding request (for Project 5) directly addresses the needs of the growing COVID-19 pandemic, with the base theme of natural fibers as filtration media for personal protection. The rapid spread of the COVID-19 pandemic exponentially increases the risk to the P42 community not only from the soil/air contamination with particulate matter and heavy metals, but now the added risk of the virus. Providing low cost reusable and biodegradable personal protection equipment (PPE) solutions to the community will be of immense value. One of the most needed items are PPE masks not only for the health care provider but the public at large. There is growing use of masks of all make ups and configurations, and their use is going to multiply exponentially. The various federal briefings have emphasized the need for a mask for every person, and over 500 million masks could be worn on daily basis world-wide. Hundreds of millions of N95 masks are in production and use worldwide. For the most part, these are disposed after single use (2-3 times at the most) which will result in gigantic quantities in landfill. This will result in massive detrimental environmental implications for years to come. In this project we propose innovative yet practical science to develop natural fiber (biobased) biodegradable filter materials that will meet the NIOSH standards for N95 filter efficiency (FE). The biobased solution is based on sub-micron regenerative cellulose natural fibers (RNCF) and small amounts of textile grade carbon fiber (TCF) that will be designed for turboelectric charging that impart the interaction to capture and kill the virus(es). The RNCF based filter material will be equally effective in lieu (or complement) of the synthetic polypropylene (PP) based 2 µm diameter, 50 grams per square meter (gsm) filter materials (not biodegradable) currently used in the N95 masks. The work will deliver a tangible full concept to product solution for implementing the RNCF material in reusable masks that the team is already developing. The entire solution will be environmentally friendly, safe and will meet NIOSH standards. The materials developed in this project will be tested against the NIOSH 42 CFR 84 for a minimum 95% filtration efficiency against solid and liquid aerosols that do not contain oil. The product will be disseminated to the P42 ecosystem including the health care providers and the community. The feedback from these groups will be sought in the form of surveys, questionnaires, training and the data will be statistically analyzed and become a part of the main P42 grant. The project is collaborative between The University of Tennessee (UT), Oak Ridge National Laboratory (ORNL), University of Alabama at Birmingham and the P42 community.
