  Abstract

The current 3-ply facemasks are produced mostly using polypropylene (PP) as the main plastic layer that is a non-biodegradable polymer. The objective of this study was to fabricate a polylactic acid (PLA) layer, a biodegradable polymer, using the electrospinning process. Comparison on the degradation trend of PLA layer and PP layer obtained from commercial 3-ply face mask (CFM) layer in seawater, river water, soil, and compost environment for a total of 60 days was observed. Results showed that the electrospinning method can produce PLA layers with similar thickness with current CFM layer, narrow distribution of fi ber diameter, and slightly dense surface morphology comparable to the CFM. Synthesized PLA fi ber layer shows 68.6%, 39.8%, and 415.7% improvement in tensile strength, Young셲 modulus, and elongation at break, respectively, compared to CFM samples. Meanwhile, for the degradation study, PLA samples show more signifi cant changes on its morphology corresponding to the degradation process that occurred on its fi bers in the seawater, river water, and soil environment, whereas for the weight change study, only the soil environment shows signifi cant changes after 45 days. In contrast, CFM samples did not show any signifi cant changes corresponding to degradation activity.
