High‐Temperature Bearable Polysulfonamide/Polyurethane Composite Nanofibers’ Membranes for Filtration Application

Frontispiece: In article number 2100081, Jinfa Ming, Xin Ning, and co-workers report polysulfonamide/polyurethane (PSA/TPU) composite nanofiber membranes with hightemperature resistance and excellent elasticity (stress 13.66 ± 1.43 MPa, and strain 75.01 ± 3.78%). Under high temperature (>200 °C) treatment, they exhibit high filtration efficiency (>99%) and a low pressure drop (133 Pa) for aerosol particles at 4 m3 h−1 airflow velocity.
