Electreted Fibrous Membranes for Effective Filtration of Fine Particles

摘要：

　　We report a novel electreted polyetherimide-silica (PEI-SiO2) fibrous membrane by a single-step strategy to achieve effective filtration of fine particles.The hierarchical structured PEI-SiO2 membranes were endowed with promising superhydrophobicity.Unlike the commercial PP-based filter media, the as-prepared membranes can be treated at 200 ℃ for30 min without sacrificing filtration efficiency (99.992%) and pressure drop (61 Pa) owing to the combined contribution of polarization and space charges.
