Nanofibrous Porous Organic Polymers and Their Derivatives: From Synthesis to Applications

Advanced Science, Год журнала: 2024, Номер 11(19)

Опубликована: Март 12, 2024

Abstract Engineering porous organic polymers (POPs) into 1D morphology holds significant promise for diverse applications due to their exceptional processability and increased surface contact enhanced interactions with guest molecules. This article reviews the latest developments in nanofibrous POPs derivatives, encompassing polymer nanofibers, composites, POPs‐derived carbon nanofibers. The review delves design fabrication strategies, elucidates formation mechanisms, explores functional attributes, highlights promising applications. first section systematically outlines two primary approaches of POPs, i.e., direct bulk synthesis electrospinning technology. Both routes are discussed compared terms template utilization post‐treatments. Next, performance derivatives reviewed including water treatment, water/oil separation, gas adsorption, energy storage, heterogeneous catalysis, microwave absorption, biomedical systems. Finally, highlighting existent challenges offering future prospects concluded.

Nanostructured hypercrosslinked porous organic polymers have triggered immense research interest for a broad spectrum of applications ranging from catalysis to molecular separation. However, it still remains challenge tune their nanoscale morphology. Herein, we demonstrated remarkable variation morphologies triptycene-based microporous starting irregular aggregates (FCTP) rigid spheres (SCTP) two-dimensional nanosheets (SKTP) three distinct polymerization methodologies, Friedel-Crafts knitting using an external crosslinker, Scholl reaction, and solvent knitting, respectively. Further, the dramatic role reaction temperatures, catalysts, solvents resulting in well-defined was elucidated. Mechanistic investigations coupled with microscopic computational studies revealed evolution 2D highly solvent-knitted polymer (SKTP, 2385 m2 g-1), sequential hierarchical self-assembly nanospheres nanoribbons. A structure-activity correlation sulfonated counterparts removal toxic polar micropollutants water delineated based on chemical functionalities, specific surface area, pore size distribution, dispersity, Furthermore, sheet-like (SKTPS) exhibited rapid adsorption kinetics (within 30 s) large array micropollutants, including plastic components, steroids, antibiotic drugs, herbicides, pesticides uptake capacity excellent recyclability. The current study provides impetus designing morphology-controlled functionalized task-specific applications.
