Given the pervasiveness of air pollution with varying components and the shortcomings of conventional air filter mats, multifunctional air filters are becoming increasingly important. This has led to the development of air filter nanofabrics comprising bio-based components (such as chitin and proteins) and polymers (such as polyvinyl alcohol and pullulan). Electrospun air filter nanofabrics containing pea protein isolate (PPI) and polyvinyl alcohol (PVA) have yet to be developed to the researchers’ knowledge. In this study, the potential electrospinnability and filtration capabilities of PPI and PVA were assessed and elaborated via a systematic review. Since PPI’s globular morphology lacks molecular entanglement, PVA, an auxiliary spinning polymer with protein binding capabilities, is needed to aid PPI. Combining the two has successfully produced electrospun homogenous nanofabrics. Additionally, the nanofabrics likely possess physical and chemical filtration capabilities due to desirable material properties and powerful intermolecular interactions. Thus, PPI/PVA nanofabrics show great potential for multifunctional air filtration applications.
