Abstract The development of photocatalytic membranes using electrospinning technology has significantly advanced their practical applications. However, current are encountering the issues poor mechanical property in non‐elastic fiber and low charge carrier separation efficiency non‐conductive polymer. Through improving thermoplastic polyurethane (TPU) precursor dissolution adding conductive polyaniline (PANI) respectively before after electrospinning, TiO 2 ‐based elastic (EC) TPU with higher strength performance created, compared to traditional inelastic (IN) membrane, even (IC) membrane. nanofibers EC membrane have a relatively rough surface structure, which exposes more catalytic sites. Ultraviolet photoelectron spectrum (UPS) test results show that work function ( φ ) becomes lower than IN IC membranes, leading strongest electron transfer potential for reactions. For degradation Methyl Orange (MO), demonstrates best rate 49.43% over 3 days among three samples. These findings suggest is promising in‐site micropollutant water treatment real‐world.

Abstract Developing high‐performance, low‐resistance, and recyclable air filtration materials remains a formidable challenge. Herein, silica nanoparticles (SiO 2 NPs) supramolecular complexes consisting of melamine (MA) trimesic acid (TMA) are constructed as SiO @MA·TMA nanofibrous composite membrane via thermally induced precursor process (TIPC) for efficient particulate matter (PM) removal. Hydrophilic NPs additional nucleation mediators can not only promote the growth MA·TMA nanocrystalline fibers by shortening interfacial free energy thus reducing barrier, but also increase fiber surface roughness constructing hierarchical structure membrane. Under synergy NPs, membranes possess high efficiency 99.82% PM 1 , 99.96% 2.5 99.98% 10 with low resistance (153 Pa, <0.15% standard atmospheric pressure). Taking advantage reversible property complexes, closed‐loop recycling realized. Only green solvents (water ethanol) involved in TIPC process, making this strategy environmentally‐friendly cost‐effective. This work provides an innovative preparation materials, opens avenue development high‐performance filters.

Hierarchically mesostructured nonwovens with complex fiber morphologies are gaining more and interest for filtration applications as the increased surface area offers improved efficiencies particulate matter. Several concepts known to fabricate such morphologies; however, control over morphology remains challenging. Here, we report on preparation of decorated defined supramolecular nanofibers by physical vapor deposition a selected commercially available 1,3,5-benzenetrisamide (BTA). Using polymer support, show that this solvent-free process, nanofiber length can be tuned from 5 20 μm depending evaporation time resembling bottlebrush-like mesoscale. Whereas model nonwoven is unsuitable capture matter, an increasingly efficiency up 87% 2.0 particles at low pressure drop 90 Pa. Since BTA has pronounced thermal stability, also enables temperature-resistant using glass microfiber support. We well maintained even after heat treatment 200 °C 24 h. This cannot realized based commodity polymers engineering plastics. These results prove general applicability vapor-deposited broaden application window in field separation toward efficient, robust, selective filter media.
