“…Nayak et al utilized [ 28 ] high-temperature electrospinning and post-treatment methods by a rotary rod collector to prepare axially elongated microfibrillar yarn. It is found that post-processing reduces fiber diameter while significantly improving molecular chain orientation, forming a microfiber structure that extends in the stretching direction.…”

Due to its designable nanostructure and simple and inexpensive preparation process, electrospun nanofibers have important applications in energy collection, wearable sports health detection, environmental pollutant detection, pollutant filtration and degradation, and other fields. In recent years, a series of polymer-based fiber materials have been prepared using this method, and detailed research and discussion have been conducted on the material structure and performance factors. This article summarizes the effects of preparation parameters, environmental factors, a combination of other methods, and surface modification of electrospinning on the properties of composite nanofibers. Meanwhile, the effects of different collection devices and electrospinning preparation parameters on material properties were compared. Subsequently, it summarized the material structure design and specific applications in wearable device power supply, energy collection, environmental pollutant sensing, air quality detection, air pollution particle filtration, and environmental pollutant degradation. We aim to review the latest developments in electrospinning applications to inspire new energy collection, detection, and pollutant treatment equipment, and achieve the commercial promotion of polymer fibers in the fields of energy and environment. Finally, we have identified some unresolved issues in the detection and treatment of environmental issues with electrospun polymer fibers and proposed some suggestions and new ideas for these issues.

This review explores the use of Ultra-High Molecular Weight Polyethylene (UHMWPE) fiber cloth as an innovative solution for the repair and reinforcement of concrete structures. UHMWPE is a polymer formed from a very large number of repeated ethylene (C2H4) units with higher molecular weight and long-chain crystallization than normal high-density polyethylene. With its superior tensile strength, elongation, and energy absorption capabilities, UHMWPE emerges as a promising alternative to traditional reinforcement materials like glass and carbon fibers. The paper reviews existing literature on fiber-reinforced polymer (FRP) applications in concrete repair in general, highlighting the unique benefits and potential of UHMWPE fiber cloth compared to other commonly used methods of strengthening concrete structures, such as enlarging concrete sections, near-surface embedded reinforcement, and externally bonded steel plate or other FRPs. Despite the scarcity of experimental data on UHMWPE for concrete repair, this review underscores its feasibility and calls for further research to fully harness its capabilities in civil engineering applications.

The fatigue behavior of poly (ethylene terephthalate) industrial fibers is a key issue in their long‐term service for engineering applications. To have a comprehensive understanding of the fatigue behavior, the high‐tenacity (HT) and low‐shrinkage (LS) PET fibers were selected to analyze the room temperature dynamic fatigue properties with different stress. Various techniques such as WAXD/SAXS and FTIR were employed to study the multiscale structure changes to disclose the fatigue mechanisms. Although the crystalline structure including orientation and crystallinity did not change, the amorphous structures varied with fatigue stress. The HT fiber exhibited a higher fatigue recovery ratio. The slight increase in amorphous orientation, and amorphous thickness was attributed to the oriented coiled molecular chains during tensile fatigue stress. In contrast, the LS fiber experienced plastic fatigue deformation with a lower recovery ratio. The molecular chains in the large amorphous domain are easily extended and oriented under tensile loading, increasing amorphous orientation and lamellar thickness. The fatigue mechanism for the LS fiber involved the conformation transition from gauche to trans conformers and a higher proportion of irreversible amorphous regions were formed. It is indicated that developing industrial filaments with small amorphous orientation and content is crucial to improving their fatigue resistance.
