However, it is unfortunate that the attainment of high-performance piezoelectric materials through this method remains a challenging task. Herein, a high-performance composite nanofiber membrane with a coherent and uniformly dispersed two-dimensional network topology composed of polyvinylidene fluoride (PVDF)/dopamine (DA) nanofiber membranes and ultrafine PVDF/DA nanofibers was successfully fabricated by the electrospinning technique. Based on the evidence obtained from simulations, experimental and theoretical results, it was confirmed that the unique structure of the nanofiber membrane significantly enhances the piezoelectric performance. The present PVDF/DA composite nanofibers demonstrated a remarkable piezoelectric performance such as a wide response range (1.5–40 N), high sensitivity to weak forces (0–4 N, 7.29 V N<sup>−1</sup>), and outstanding operational durability. Furthermore, the potential application of the present PVDF/DA membrane as a flexible wearable sensor for monitoring human motion and subtle physiological signals has also been validated. This work not only introduces a novel strategy for the application of electrospun nanofibers in sensors but also provides new insights into high-performance piezoelectric materials.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"6 4","pages":"1212 - 1228"},"PeriodicalIF":17.2,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42765-024-00415-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140837822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the extensive research efforts, challenges remain regarding the stably high-yield solar treatment of high-salinity water on a large scale. Here, we demonstrate an interconnected porous fabric-based scalable evaporator with asymmetric wetting properties fabricated by weaving technique for high-efficiency and salt-rejecting solar high-salinity brine treatment. Three-dimensional interconnected micropores ensure effective convection-induced fast vapor diffusion, leading to a high evaporation rate in the natural environment with the convective flow. The Janus structure effectively separates absorption and evaporation surfaces for stable salt resistance even under fast evaporation. It is observed that the evaporator achieves a high evaporation rate of 2.48 kg m<sup>−2</sup> h<sup>−1</sup> under 1-sun illumination and airflow of 3 m s<sup>−1</sup> when treating 15 wt% saline. Notably, the outdoor experiment demonstrates that there is neither salt precipitation on the surface nor a decrement in evaporation rate during the 5-day evaporation until water and solute have completely been separated. The interconnected porous fabric with asymmetric wetting properties can be easily and massively produced by industrialized weaving techniques, showing great potential for scalable and efficient solar water treatment of high-salinity brine and industrial wastewater.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":459,"journal":{"name":"Advanced Fiber Materials","volume":"6 4","pages":"1162 - 1173"},"PeriodicalIF":17.2,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140659538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
