“…[ 278 , 279 , 280 , 281 ] TENG has the capability of converting mechanical energy from all kinds of mechanical movements into electricity through triboelectrification and electrostatic induction effect, which has great potential in a great variety of practical applications. [ 282 ] But recently TENGs have also attracted significant research attention due to their potential application to face masks and respirators in order to prolong service time and enhance filtration efficiency, [ 283 , 284 , 285 , 286 , 287 , 288 ] as shown in Figure 6f . This application has become even more pertinent during the COVID‐19 pandemic.…”

Sustainable solutions on fabricating and using a face mask to block the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) spread during this coronavirus pandemic of 2019 (COVID‐19) are required as society is directed by the World Health Organization (WHO) toward wearing it, resulting in an increasingly huge demand with over 4 000 000 000 masks used per day globally. Herein, various new mask technologies and advanced materials are reviewed to deal with critical shortages, cross‐infection, and secondary transmission risk of masks. A number of countries have used cloth masks and 3D‐printed masks as substitutes, whose filtration efficiencies can be improved by using nanofibers or mixing other polymers into them. Since 2020, researchers continue to improve the performance of masks by adding various functionalities, for example using metal nanoparticles and herbal extracts to inactivate pathogens, using graphene to make masks photothermal and superhydrophobic, and using triboelectric nanogenerator (TENG) to prolong mask lifetime. The recent advances in material technology have led to the development of antimicrobial coatings, which are introduced in this review. When incorporated into masks, these advanced materials and technologies can aid in the prevention of secondary transmission of the virus.

“…A major contributor to this problem is the commonly used SFM, which comprises undegradable petro-based polypropylene (PP) melt-blown filter media [11] . This type of filter media can effectively capture ultrafine particles through electrostatic adsorption because it is charged after electret treatment.…”

“…3 e and 3f), [ 62 ] without losing much breathability. The typical approaches to introduce electrical potential in face mask include mounting TENGs 63 , 64 and integrating electret materials (PVDF, BaTiO 3 et al), 62 , 65 , 66 by which voltage of several hundred volts could be generated under the respiration air flow. Since in both ways the generated electrical potential increases with the speed of air flow, which further raises the adsorption efficiency of PMs, the deterioration of filtration efficiency under high speed air flow could be largely prevented [ 62 ] .…”

The outbreak of Covid-19 pandemic has aroused tremendous attention towards personal protective equipment (PPE) in both scientific research and industrial manufacture. Despite decades of development in PPE design and fabrication, there’s still much room for further optimization, in terms of both protection performance and wear comfort. Interdisciplinary efforts have been devoted in this research field in recent years. Significantly, the innovation of materials, which brings about improved performance and versatile new functions for PPEs, has been widely adopted in PPE design. In this minireview, recent progress in the development of novel materials and structural designs for PPE application are presented in detail, with the introduction of various material-based strategies for different PPE type, as well as the examples which applies auxiliary components into face masks to enrich the functionalities and improve the personal feelings in pandemic period.
