Prospects for Further Development of Face Masks to Minimize Pandemics Functionalization of Textile Materials with Biocide Inorganic Nanoparticles: A Review

Characterization and photocatalytic activity of TiO2 nanoparticles on cotton fabrics, for antibacterial masks

“…The development of fabrics with antibacterial and antiviral activity and self-cleaning properties has been triggered in the last decades due to healthcare industry and home textiles applications (Hussain 2020 ; Yocupicio-Gaxiola et al 2021 ; Konda et al 2020 ; Botequim et al 2012 ; Montazer and Seifollahzadeh 2011 ). Moreover, the current COVID-19 pandemic caused by the SARS-CoV-2 virus has potentiated the exhaustive research on this type of functionalized fabrics since these ones could help avoiding the virus dispersion (Yocupicio-Gaxiola et al 2021 ; Militky et al 2021 ). The cotton fabrics are the main textile used in the healthcare industry since the cotton surface could be electrostatically charged, in an analogous way as on the natural silk surface (Konda et al 2020 ).…”

“…Also, it is important to mention that inorganic NPs may act as adsorbents, catalysts or photocatalysts, which could enhance or promote high antibacterial activity. Currently, inorganic NPs and their composites are a viable alternative to manufacture multifunctional and antiviral fibers (Hussain 2020 ; Yocupicio-Gaxiola et al 2021 ). Among others inorganic NPs, TiO 2 nanoparticles (TiO 2 -NPs) have attracted attention because they are biocompatible, non-toxic, and inexpensive (Yocupicio-Gaxiola et al 2021 ).…”

The incorporation of TiO 2 -NPs on textile fibers provides them with antiviral properties, UV protection, promotes surface hydrophobicity/hydrophilicity, could act as flame retardant, and provide self-cleaning properties (Hussain 2020 ; Yocupicio-Gaxiola et al 2021 ; Montazer and Seifollahzadeh 2011 , Lessan et al 2011 ; Senić et al 2011 ).…”

The antibacterial activity of TiO 2 -NPs is attributed to the fact that they can produce reactive oxygen species (ROS) in the presence of UV irradiation, since TiO 2 -NPs is a semiconductor material, acting as a photocatalyst.…”

Textile Functionalization Using LTA and FAU Zeolitic Materials

“…These devices can be transformed from passive filters into active protection. For this purpose, it is enough to apply materials with an oligodynamic effect on the fabric of the masks, which makes it possible to destroy infectious agents that have fallen on the mask with aerosol droplets from the air stream [ 1 ].…”
