Abstract：Achieving ultralow emissions requires to effectively capture fine particles from industrial flue gas and overcome the condensation and paste bag phenomena of filter bags in high-humidity environments. In this study, a novel superhydrophobic metal-organic framework (MOF)-based composite filter was constructed. Specifically, fluorinated NH2-MIL-125 was sprayed onto the surface of polyethylene terephthalate (PET) fibers to form a micro/nanoscale rough structure on the fiber surface that facilitated the rapid and firm assembly of the composite filter (SH-T@PET). The SH-T@PET had highly stable hydrophobicity, as evidenced by its water contact (WCA) and shedding angles (WSA) of (152.5±1.8)° and (6.7±1.7)°, respectively. In addition, the PM0.3removal efficiency (RE, (96.53±0.65)%) was greatly improved owing to the multiple effects of polar functional groups (-NH2), high zeta (ζ) potential, and the large void structure of NH2-MIL-125active units on the surface of SH-T@PET fibers. Moreover, the microscopic pore structure of SH-T@PET remained unchanged, the filtration pressure drop (ΔP, 50Pa) did not accelerat sharply, and the quality factor (QF, 0.0672Pa-1) was approximately 12.79% higher than that of the original PET filter at the low load rate (2.1%). The SH-T@PET composite filter media also exhibited good thermal and mechanical stabilities.
