To enhance oil−water separation efficiency, it is urgent to synthesize novel membrane materials that exhibit high flux and high retention efficiency and excellent antisolvent property. Herein, a seeding−extension−bud protrusion procedure was developed to fabricate superhydrophobic separation membranes through UVassisted grafting and covalent modification on a microporous polypropylene. The synthesized superhydrophobic membranes (PPN-HDI-TPFOS) exhibit a bud protrusion micro/nanostructure, which significantly increases the contact area between the membrane surface and the emulsion, as well as the collision among the emulsion droplets during the oil−water separation. This membrane shows high flux of up to 24 800 L m −2 h −1 for dichloromethane (DCM)/water immiscible oil−water mixtures and 6528 L m −2 h −1 for water-in-DCM emulsions, together with excellent water retention (>99%) as well as good antisolvent property. Moreover, it exhibits excellent retention rates (>98%) for other water-in-oil emulsions (kerosene, hexane, and cyclohexane). This work supplies a useful strategy to synthesize complex membrane with extremely high flux as well as high rejection rate.

Pyrene‐4,5,9,10‐tetraone (PTO), a coal tar derivative with redox‐active ortho‐carbonyl groups, has been intensively explored for sustainable organic electrodes due to its remarkably high capacity, superior redox robustness, and versatile cation storage. However, PTO often suffers from poor cycling stability due to its being soluble in organic electrolytes, which results in a detrimental shuttle effect and self‐discharge behavior. Its low electrical conductivity also results in poor rate performance, limiting practical applications. Therefore, different strategies have recently been developed to inhibit the solubility of PTO. In this review, the latest progress in enhancing the performance of PTO‐based electrodes and their applications in various battery types is presented. Firstly, a brief discussion on the relationship between the structural characteristics of PTO and its electrochemical performance is provided. Then, approaches to inhibiting the shuttle effect of molecular PTO are outlined and compared. Furthermore, the design and synthesis of PTO‐based polymer electrode materials are discussed. Finally, some perspectives and challenges are put forward regarding the performance improvement of PTO‐based electrode materials, inspiring further development of not only PTO but also other organic electrode materials in electrochemical energy storage applications.
