Extreme Orientation of Stereocomplexed Poly(lactic acid) Induced Ultrafine Electroactive Nanofibers for Respiratory Healthcare and Intelligent Diagnosis

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(24), P. 9290 - 9300

Published: June 5, 2024

Biodegradable and renewable poly(lactic acid) (PLA) fibrous membranes have emerged as a promising approach to replace traditional polymeric air filters, but are still challenged by relatively low electroactivity poor electret properties. Herein, we disclose an effective electrospinning strategy substantially promote the extreme orientation of stereocomplexed PLA (OSC-PLA), conferring significant alignment refinement electrospun nanofibers (diameter ∼370 nm), well facilitate formation electroactive phases (i.e., β-phase, phase, stereocomplex crystals). Benefiting from well-tailored morphology remarkable electroactivity, OSC-PLA nanofibrous (NFMs) were characterized largely improved dielectric properties, surface potential (over 3.64 kV), PM0.3 filtration properties (93.33% at 85 L/min) compared pure PLLA membrane (2.01 kV 80.21%). It enabled assembly triboelectric nanogenerator (TENG) filters using NFMs active layer, yielding excellent charge regeneration mechanisms output current nearly 80 nA, driven respiratory vibrations L/min, thus permitting high humidity resistance, exemplified removal efficiency 95.02% RH 90%. Moreover, deep machine learning man–machine interaction integrated with OSC-PLA-based TENGs, demonstrating long-term monitoring high-precision diagnosis (accuracy 96.88%) various patterns. The proposed ecofriendly ultrafine highly appealing for sustained healthcare self-powered intelligent diagnosis.
