Summary: Designing large-area flexible transparent smart windows for high-efficiency indoor fine particulate matter (PM2.5) capture is important to guarantee safe indoor environments. In this article, we demonstrate that large-area fabrication of flexible transparent Ag-nylon mesh can be performed not only to turn the indoor light illumination intensity as thermochromic smart windows after uniformly coating with thermochromic dye but also to purify indoor air as high-efficiency PM2.5 filter. It takes only about $15.03 and 20 min to fabricate 7.5-m2 Ag-nylon flexible transparent windows without any modification with a sheet resistance of as low as 8.87 Ω sq−1 and optical transmittance of 86.05%. As an excellent PM filter (can be recycled after PM filtration), the removal efficiency is as high as 99.65% and the processing speed is high, which can reduce the PM2.5 density from heavily polluted (248 μg·m−3, purple alert) to good (32.9 μg·m−3, green statement) in 50 s. : Environmental Nanotechnology; Materials Processing; Electrical Materials Subject Areas: Environmental Nanotechnology, Materials Processing, Electrical Materials
