Hierarchical dual-nanonet of polymer nanofibers and supramolecular nanofibrils for air filtration with a high filtration efficiency, low air resistance and high moisture permeation

Hierarchical dual-nanonets are fabricated through self-assembly of supramolecular nanofibrils onto solution-blown PAN nanofiber mat, demonstrating high porosity, small pore size, high filtration efficiency and boosted moisture permeation.
