The COVID-19 pandemic has brought enormous human and economic costs. Limiting its transmission rate within the population is the most critical task in its control, as reducing the total number of infections at any given time can prevent the healthcare system from being overburdened. Although the coronavirus is airborne, it can survive on certain types of common surfaces for days, leading to a significant risk of surface transmission. Our goal is to develop a technology of coating materials surfaces with antiviral polymers, which quickly inactivates viruses after contact. This coating can be applied to furniture, flooring, and other general surfaces in public spaces to reduce the risk of contamination and transmission. It will also enable the development of a new generation of personal protective equipment (PPE) with built-in antiviral properties. The proposed work targets a central challenge in the formulation design of this technology. It will combine computer simulation with experiments to understand, at the molecular level, how certain types of polymers dismantle coronavirus particles. Meanwhile, consideration will also be given to evaluate their suitability for coating on substrate surfaces in terms of interfacial and mechanical properties. The direct outcome of this project will be a clear set of molecular guidelines on the ideal polymer chemical structure for such an application, which is essential for our continued formulation development of this coating material.

COVID-19疫情带来了巨大的人力和经济成本。限制其在人群中的传播率是其控制中最关键的任务，因为在任何特定时间减少感染总数可以防止医疗系统负担过重。虽然冠状病毒是空气传播的，但它可以在某些类型的常见表面上存活数天，导致表面传播的重大风险。我们的目标是开发一种在材料表面涂上抗病毒聚合物的技术，这种聚合物在接触后迅速灭活病毒。这种涂料可应用于家具、地板和公共空间的其他一般表面，以降低污染和传播的风险。它还将有助于开发具有内置抗病毒特性的新一代个人防护设备（PPE）。拟议的工作针对的是该技术配方设计中的一个核心挑战。它将联合收割机与实验相结合，在分子水平上了解某些类型的聚合物如何分解冠状病毒颗粒。同时，还将考虑从界面和机械性能方面评估它们在基材表面上涂覆的适用性。该项目的直接成果将是为此类应用提供一套关于理想聚合物化学结构的明确分子指导方针，这对于我们继续开发该涂料配方至关重要。
