This work shows that the adsorptive performance of fibrous membrane can be enhanced by microporous organic network (MON) chemistry. Copper species are introduced into the surface of poly(ethylene terephthalate) (PET) fibers through electroless deposition. Through the Cu 2 O‐catalyzed click reactions of tetra(4‐ethynylphenyl)methane with 1,4‐diazidobenzene, click‐based MON (C‐MON) layers are formed on the PET@Cu@Cu 2 O. Etching of copper species results in the formation of PET@C‐MON membranes that show enhanced removal performance by up to 13.3 times for particulate matters with smaller sizes than 2.5 µm (PM 2.5 ), compared with pristine PET fibers.
