Stereocomplexation-Enhanced Electroactivity of Poly(lactic acid) Nanofibrous Membranes for Long-Term PM Capturing and Remote Respiratory Monitoring

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(9), P. 3554 - 3564

Published: Feb. 1, 2024

Development of poly(lactic acid) (PLA) nanofibrous membranes (NFMs) holds great potential to replace the conventional nondegradable air filters, but is largely thwarted by intrinsically low electroactivity and poor electret properties PLA. Here, highly electroactive PLA NFMs coupling triboelectric nanogenerator (TENG)-based recharging mechanisms are demonstrated for long-term respiratory protection from fine ultrafine particulate matters (PM0.3 PM2.5), as well wireless intelligent monitoring physiological characters. To enhance in situ self-charging NFMs, we proposed a stereocomplexation strategy involving direct electrospinning PLLA/PDLA nanofibers (approaching 500 nm), conferring remarkable promotion phases, dielectric properties, surface (over 10 kV), output (nearly 20 V at humanoid breathing conditions). Benefiting well-tailored morphology features, exhibited high (180 V) excellent filtration performance (96.32% PM2.5 92.09% PM0.3) while providing desirable resistance (only ∼200 Pa even 85 L/min), far surpassing those pristine PLLA counterpart (60 V, 72.92%, 281 Pa, respectively). This was accompanied high-sensitivity vivo cardiorespiratory characters such coughing breathing, essentially arising respiration-triggered distinct TENG mechanisms. Featuring efficient noninvasive monitoring, our biodegradable appealing healthcare real-time monitoring.
