In this study design and fabrication of coronavirus filter based on the cellulose and carbon nanomaterials have been investigated. Particulate matter (PM) corona virus has attracted a lot of attention due to its great threat to human health. Nanoparticles are intertwined with fibers and form highly porous air filter paper. The structure of the filter has been characterized using scanning electron microscope (SEM) and Brunauer-Emmett-Teller (BET) analysis. In addition, by optimization with activated carbon (AC) nanoparticles, the prepared AC air filter paper shows a high removal efficiency of more than 95% for PM 100 nm. More importantly, this filter shows less pressure drop and less thickness. This filter has a positive effect on the prevention of this disease during the coronavirus epidemic and show high absorption efficiency air filter for PM more than 100 nm.
在本研究中，对基于纤维素和碳纳米材料的冠状病毒过滤器的设计与制造进行了研究。颗粒物（PM）冠状病毒因其对人类健康的巨大威胁而备受关注。纳米颗粒与纤维交织在一起，形成了高度多孔的空气滤纸。已使用扫描电子显微镜（SEM）和布鲁诺尔-埃米特-泰勒（BET）分析对过滤器的结构进行了表征。此外，通过用活性炭（AC）纳米颗粒进行优化，制备的AC空气滤纸对100纳米的PM显示出超过95%的高去除效率。更重要的是，这种过滤器显示出较小的压降和较小的厚度。这种过滤器在冠状病毒流行期间对预防这种疾病有积极作用，并且对大于100纳米的PM显示出高吸收效率的空气过滤器。
