Flexible, Breathable and Hydrophobic SnO2–SnS2–SiO2/SiO2 All-Inorganic Self-Supporting Nanofiber Membrane for Ultralow-Concentration NO2 Sensing Under High Humidity (Adv. Funct. Mater. 4/2025)
Nanofiber Membranes
In article number 2410833, Hongbing Lu, Jianzhi Gao, Hongjun Wang, Benpeng Zhu, and co-workers develop a two-spinneret electrospinning and thermal sulfidation method to create an all-inorganic self-supporting nanofiber gas sensor. This sensor features high flexibility, breathability, humidity resistance, and structural stability, offering exceptional sensitivity and selectivity for detecting ultralow NO2 levels in exhaled breath, crucial for monitoring asthma-related illnesses.
