Abstract The production of bio‐alcohol is increasingly gaining international attention due to its potential as a viable alternative fossil fuels and ability mitigate carbon dioxide emissions. However, the cost almost double that fuels, primarily because low yield purification process. Herein, high‐performance scalable organosilicon membrane with high chain flexibility controllable crosslinking density developed for energy‐efficient alcohol purification. synthesized achieves an ultrahigh total flux (5.8 kg·m −2 ·h −1 ) comparable separation factor (8.7) ethanol/water separation, outperforming most state‐of‐the‐art polymer‐based membranes. Integrated experiments molecular dynamics simulations confirm ultrafast permeation originates from flexibility, large fractional free volume, weak interactions between feed molecules universal applicability low‐crosslinking mechanism formation membranes also validated. Moreover, efficiency scalability in production, along stability casting solution, offer promising prospects industrial applications.

Oriented 2D metal-organic framework (MOF) membranes hold considerable promise for industrial separation processes. Nevertheless, the lattice misalignment caused by twisted stacking of nanosheets reduces in-plane pore size and exerts a significant impact on membrane performance. Precisely regulating pattern oriented MOF remains challenge. Here, scalable scrape-coating technique supplemented vapor untwisting strategy is proposed to directly construct non-twisted ultrathin Zr-BTB (Zr-BTB-M) polyvinylidene fluoride (PVDF) substrates. The are induced undergo reorganization during coating process, resulting in highly overlapped lattices largest channels. exceptional butyl acetate selective adsorption capacity Zr-BTB, combined with its provision ordered vertical penetrating pathways, significantly enhances molecular transport. After facile polydimethylsiloxane (PDMS) coating, pervaporation index PDMS/Zr-BTB-M/PVDF found be 9.74 times higher than that conventional PDMS/PVDF membranes, paving way innovative, high-efficiency, energy-saving technologies.
