“…A reusable mask is expected to maintain effectively after long-time use in a high-moisture environment or after disinfection. Most nanofiber filters, such as polyacrylonitrile(PAN) [ 111 ], poly (ε-caprolactone)(PCL) [ 112 ] and poly (vinylidene fluoride)(PVDF) [ 113 , 114 ], can withstand water washing and alcohol sterilization. Recently, Ullah et al compared the melt-blown filter with nanofiber filter through cleaning them with 75% ethanol to evaluate their reusability [ 64 ].…”

The outbreak of Coronavirus Disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has triggered great global public health concern. Face masks are essential tools to reduce the spread of SARS-CoV-2 from human to human. However, there are still challenges to prolong the serving life and maintain the filtering performance of the current commercial mask. Filters composed of ultrafine fibers with diameter down to tens of nanometers have the potential to physically block viruses. With adjustable composition and nanostructures, the electrospun ultrafine fiber filter is possible to achieve other necessary functions beyond virus blocking, such as antiviral, transparent, and degradable, making it an important part of fighting the epidemic. In this review, beginning with the basic information of the viruses, we summarize the knowledge of masks and respirators, including the filtering mechanism, structure, classification, and standards. We further present the fabrication method, filtering performance, and reusable potential of electrospun ultrafine fiber-based masks. In the end, we discuss the development directions of ultrafine fibers in protective devices, especially their new functional applications and possible contributions in the prevention and control of the epidemic.

“…The nanobre structure is intact even aer contact with water for 72 h, and a concentration beyond 1% (w/ w) of CuO is toxic. 145 Compared to individual metal and metal oxides, combinations with other metal and metal oxides have shown complete inactivation in lesser contact time. 75,88 A combination of different AMA also reduces the chances of resistant strains of microorganisms.…”

“…Furthermore, a mask often becomes a virus collector during repeated breathing activities, particularly when its outer surface is exposed to contaminated droplets [ 8 , 16 ]. Given that viruses and bacteria will stay on the surface and in the masks during wear for a considerably long period of time, it is obviously dangerous and undesirable if they can live safely and remain active in the warm and humid microenvironment in the masks.…”

The masks have always been mentioned as an effective tool against environmental threats. They are considered as protective equipment to preserve the respiratory system against the non-desirable air droplets and aerosols such as the viral or pollution particles. The aerosols can be pollution existence in the air, or the infectious airborne viruses initiated from the sneezing, coughing of the infected people. The filtration efficiency of the different masks against these aerosols are not the same, as the particles have different sizes, shapes, and properties. Therefore, the challenge is to fabricate the filtration masks with higher efficiency to decrease the penetration percentage at the nastiest conditions. To achieve this concept, knowledge about the mechanisms of the penetration of the aerosols through the masks at different effective environmental conditions is necessary. In this paper, the literature about the different kinds of face masks and respiratory masks, common cases of their application, and the advantages and disadvantages of them in this regard have been reviewed. Moreover, the related mechanisms of the penetration of the aerosols through the masks are discussed. The environmental conditions affecting the penetration as well as the quality of the fabrication are studied. Finally, special attention was given to the numerical simulation related to the different existing mechanisms.
