Abstract：

The　environmentally　friendly,　economical,　and　efficient　production　of　high-performance　and　multifunctional　bio-based　air　filter　membranes　is　crucial　for　the　protection　of　human　health　and　sustainable　development.　However,　this　endeavor　is　significantly　limited　by　the　current　gap　in　material　selection　and　process　routes.　This　study　proposes　a　strategy　for　advanced　functionalization　and　structural　optimization　of　ethyl　cellulose　(EC)　to　effectively　develop　a　high-performance,　fully　bio-based　air　filter　membrane　exhibiting　superior　antibacterial　properties.　Through　the　minimal　interference　method,　konjac　glucomannan　(KGM)　and　curcumin　(Cur)　were　blended　with　EC,　which　preserved　the　bimodal　fibers　to　the　highest　degree.　By　green　electrospinning　in　one　step,　the　quality　factor　of　EC/KGM/Cur　membranes　reached　0.101　Pa−1,　the　antibacterial　activity　against　Escherichia　coli　and　Staphylococcus　aureus　reached　＞99.6　%,　and　the　productivity　of　EC/KGM/Cur　membranes　prepared　by　using　sheath　gas　was　increased　by　almost　14.73　times.　This　study　offers　a　sustainable,　scalable,　and　versatile　manufacturing　approach　for　air　filters　and　thus　a　promising　solution　to　the　urgent　need　for　environmentally　friendly　and　efficient　filter　systems.　©　2025　Elsevier　Ltd
