Bridged Conductive Nanofibrous Membrane Overcoming the Porosity-Conductivity Trade-Off for Electrothermal Air Purification.

ABSTRACT: Emerging conductive porous materials hold remarkable promise for Joule-heating applications like electothermal filtration, smart textiles, and energy management due to their porous and conductive synergy. However, their development is constrained by a design trade-off between achieving high porosity for efficient flow transmission and maintaining a conductive network for effective charge transport. To overcome this, a bridged conductive nanofibrous membrane (BCNM) by linking polypyrrole-coated nanofibers via self-assembled polypyrrole nanowires is developed. This dual-state network establishes continuous electron pathways while preserving multiscale porous channels, orchestrating air permeation, particulate capture, and electrothermal sterilization for all-in-one air purification.
