Abstract The development of advanced oil sorbents with superior thermal stability, high adsorption capacity, and excellent reusability is crucial for addressing hot leakage challenges, particularly in the petrochemical machinery industries. This study presents a novel polyimide (PI) nanofiber aerogel (PIF-a) designed high-temperature absorption. Utilizing electrospinning post-treatment, PIF-a exhibits hierarchical pore structure, ultralow density, remarkable flexibility. At room temperature, demonstrates an capacity 83.1 g/g, surpassing conventional materials. Notably, retains structural integrity up to 250°C, 78.6 g/g at 200°C. Despite repeated adsorption-desorption cycles, PIF-a's remains stable, retaining over 90% its initial performance. breakthrough material, exceptional rapid kinetics, durable reusability, represents significant advancement absorption technology, broadening application potential nanofiber-based materials environmental spill emergencies.

Abstract A series of composite materials, ETB@CNT (ETB@CNT10, ETB@CNT20, ETB@CNT30, ETB@CNT40, ETB@CNT50) with different carbon nanotubes (CNTs) contents are successfully prepared by using one‐pot method. Compared the pure ET‐B‐COF, which is a ketoenamine‐linked covalent organic framework (COF) positive charge structure, CNTs can effectively improve electrochemical performance and specific capacitance increased increase mass added during preparation process. Among them, ETB@CNT40 exhibits best (37.6 F g −1 ) at current density 1 . This study indicates that simultaneous introduction into COFs significantly materials.
