Excessive usage from disposable medical face masks has significantly contributed to the global plastic waste issue since outbreak of COVID-19 pandemic. As a main ingredient in manufacturing process masks, non-renewable polypropylene (PP) polymer poses environmental challenges. Additionally, PP-based electrostatic filter, known for its high filtration efficiency, cannot maintain effectiveness long periods service. In this research, we demonstrate potential dextrin, biomass-derivative, as more sustainable alternative PP electret. Due dextrin being produced natural starch products, it is renewable material that biocompatible and eco-friendly. The hydrophilic rich content hydroxyl groups allows be processed environmentally friendly way with water. However, hydrophobic electret filter preferred prevent sharp decrease efficiency. By adding sodium methylsiliconate (SMS), hydrophobicity blended dextrin-SMS can inherent prolonged charges over 100 days. Ultimately, non-woven nanofiber using successfully an industrial compatible electrospinning technique combined addition polyethylene oxide (PEO) enhance electrospinability filter.
