Summary: The electrospinning of polymer nanofibers, especially biodegradable cellulose acetate (CA) nanofibers, has attracted significant attention due to their unique properties and a wide range of applications. However, the conventional electrospinning process involves the use of toxic solvents and additives. In this study, we developed a green solvent system and used biosurfactants to improve the electrospinning process and obtain uniform and porous CA nanofibers. The nanofiber diameter and porous texture could be adjusted by tuning the solvent ratio, and the resulting nanofibers showed tunable degradation properties.

Summary: This article summarizes the latest advances in materials and designs used for face masks. It focuses on face masks based on nanomaterials and designs. Among them, face masks based on electrospun nanofiber-based membrane materials have gained attention due to their nano-sized pores, light weight, and high filtration efficiency. In addition, the incorporation of metal organic framework (MOFs) and graphene has opened up new possibilities for further improvement of face masks. The application of rapid prototyping/3-dimensional (3-D) printing techniques also helps shorten the manufacturing time of face masks.
