The discovery of efficient multifunctional porous materials aiming to address societal challenges is the focus of our team. We are interested in finding new applications to these materials that can ensure the welfare of Canadians by protecting our health and environment while not relying on international manufacturing and ensuring benefits for Canada's economy. Amidst the COVID-19 pandemic, we believe that we have the answer to the urgent need for the next generation of smarter and safer personal protective equipment (PPE) based on the materials we have expertise in preparing. This proposed program aims a partnership between the Murugesu Group at the University of Ottawa and General Dynamics Ordnance and Tactical Systems - Canada Inc. (GDOTS Canada) to look at ways to protect Canadians and the environment from dangerous microorganisms dispersed in the air including the SARS-CoV-2 virus, which is easily spread especially when containment measures are not properly adopted. The virus spreads through coughing or sneezing, but also during the speech, creating a mist of small invisible droplets that can be exchanged through the respiratory tracts. Thus, as widely recommended, social distance is the best measure to control the SARS-CoV-2 virus. Nonetheless, healthcare workers on the frontlines and military need self-protection equipment to assist the population while working safely. With this in mind, this proposal encompasses the preparation, characterization, and scale-up of high performing and highly tunable porous materials termed Metal-Organic Frameworks (MOFs) and their amalgamation with polymeric microfibers at the nanoscale, aiming to implement smart filtering materials to support the fabrication of smart PPE especially for providing the frontline healthcare workers dealing with infected patients with high-performing masks, respirators, and apparel.

发现旨在解决社会挑战的高效多功能多孔材料是我们团队的重点。我们有兴趣寻找这些材料的新应用，通过保护我们的健康和环境来确保加拿大人民的福利，同时不依赖国际制造并确保加拿大经济的利益。在 COVID-19 大流行期间，我们相信，基于我们拥有专业知识准备的材料，我们可以满足对下一代更智能、更安全的个人防护装备 (PPE) 的迫切需求。该拟议计划旨在渥太华大学 Murugesu 集团与加拿大通用动力军械和战术系统公司 (GDOTS Canada) 之间建立合作伙伴关系，寻找保护加拿大人和环境免受空气中传播的危险微生物（包括 SARS）侵害的方法-CoV-2病毒，特别是在未采取适当遏制措施的情况下，很容易传播。病毒通过咳嗽或打喷嚏传播，但也在演讲过程中传播，产生可通过呼吸道交换的看不见的小飞沫。因此，正如广泛建议的那样，社交距离是控制 SARS-CoV-2 病毒的最佳措施。尽管如此，前线和军队的医护人员需要自我防护设备，以在安全工作的同时帮助民众。考虑到这一点，该提案涵盖了被称为金属有机框架（MOF）的高性能和高度可调多孔材料的制备、表征和放大，以及它们与纳米级聚合物微纤维的融合，旨在实现智能过滤材料支持智能个人防护装备的制造，特别是为处理感染患者的一线医护人员提供高性能口罩、呼吸器和服装。
