Recent Progress in Modified Polymer-Based PPE in Fight Against COVID-19 and Beyond
AI summary Read the abstract
This review covers advances in modified polymer-based personal protective equipment materials for COVID-19 and future infectious disease scenarios, examining how antimicrobial coatings, nanoparticle additives, and advanced filtration polymers can improve PPE performance while minimizing microplastic shedding.
The increasing concerns about human-health-related microbial infections and the need for the development of personal protective equipment (PPE) is becoming a major challenge. Because of their light weight and ease of processing, polymeric materials are widely used in designing and fabricating PPE that are being used by healthcare workers and the general population. Among the available PPEs, face masks have been widely developed from polymeric materials such as polypropylene, polycarbonate, and poly(ethylene terephthalate). However, currently, many of the face masks are not antimicrobial, which can pose a great risk for cross-infection as discarded masks can be a dangerous source of microbes. To prevent the spread of microbes, researchers have prompted the development of self-sterilizing masks that are capable of inactivating microbes via different mechanisms. Hence, this review provides a brief overview of the currently available antimicrobial-modified polymer-based PPE, and it mainly focuses on the different types of nanoparticles and other materials that have been embedded in different polymeric materials. The possibility of inhaling microplastics from wearing a face mask is also outlined, and the effects of various modifications on the health of face mask users are also explored. Furthermore, the effects of the disposed masks on the environment are underlined.

Review on personal protective equipment: Emerging concerns in micro(nano)plastic pollution and strategies for addressing environmental challenges
AI summary Read the abstract
This review examines how the massive increase in disposable masks, gloves, and other protective equipment during COVID-19 has become a major new source of microplastic pollution. An estimated 1.6 million tons of plastic waste per day was generated from discarded protective equipment, and as this gear breaks down, it releases micro- and nanoplastic particles into soil and water. These particles can accumulate in seafood and other organisms, creating another pathway for human microplastic exposure.
