COVID-19 is a pandemic that has caused serious disruption in almost every day-to-day life around the world, and wearing a mask is essential for human safety from this virus. However, masks are non-recyclable materials, and the accumulation of masks used every day causes serious environmental issues. In this study, we investigate the recycling of mask materials for addressing the environmental problems and transforming as a high value-added material through chemical modification of masks. The recycled mask is applied as a separator for aqueous rechargeable batteries, and shows outstanding safety and electrochemical performance than the existing separator. This approach will lead to an advanced energy technology considering nature after overcoming COVID-19.
新型冠状病毒肺炎（COVID-19）是一场大流行病，几乎给世界各地的日常生活都带来了严重干扰，佩戴口罩对于人类预防这种病毒至关重要。然而，口罩是不可回收材料，每天使用的口罩堆积会造成严重的环境问题。在本研究中，我们研究了口罩材料的回收利用，以解决环境问题，并通过对口罩进行化学改性将其转化为高附加值材料。回收后的口罩被用作水系可充电电池的隔膜，与现有的隔膜相比，表现出卓越的安全性和电化学性能。这种方法将在战胜新型冠状病毒肺炎后带来一种兼顾自然的先进能源技术。
