Abstract

We have designed and developed nonwoven fabric supported electrospun polymeric nanofibrous‐based membrane for robust filtration system for ecological sustainability of clean water. The fabricated nanocomposites filters were tested for the removal of chromium (VI) toxic heavy metal ions from contaminated feedstock water. The interpenetrating network like morphological structure obtained from pure and composite nanofibers‐based membranes have been thoroughly investigated to understand the structure–properties of highly entangled system. It has been found that incorporating functional moieties onto nanocomposite membranes significantly impacts the absorption efficiency of toxic metals. The pore sizes of the hierarchical geometries have been varied to insight into its impact on flow rate and efficiency of filtration. The strategy of interfacing the multifunctional composite polyethylene terephthalate nanofiber membrane supported on nonwoven fabric to generate heterostructures has found to provide mechanically stable platform for efficient metal ion removal. It has been found by BET surface area analysis that the nanofibers reinforced with functional nanomaterials has controlled pore geometry compared to pristine PET electrospun nanofibers which lead to higher absorption of metal ions. We have highlighted the importance of mechanically stable electrospun polymeric nanofibers membrane‐based mitigation strategies to meet the huge demand of potable water for long‐term environmental sustainability.Highlights

Mechanically toughened freestanding nanofibers mat supported on nonwoven fabric.

Functionally upgrade nanofibers by incorporation of carbon based nanofillers.

功能聚合物纳米复合膜的铬吸附效率：环境可持续性案例研究

我们设计并开发了以电纺聚合物纳米纤维为基础的无纺布膜，这种膜具有强大的过滤系统，可实现清洁水源的生态可持续性。我们对制造的纳米复合过滤器进行了测试，以去除受污染原料水中的铬（VI）有毒重金属离子。对纯纳米纤维膜和复合纳米纤维膜的互穿网络形态结构进行了深入研究，以了解高度纠缠系统的结构特性。研究发现，在纳米复合膜上加入功能分子会显著影响有毒金属的吸收效率。我们改变了分层几何结构的孔径大小，以深入了解其对流速和过滤效率的影响。研究发现，将多功能复合聚对苯二甲酸乙二酯纳米纤维膜与无纺布连接以产生异质结构的策略为高效去除金属离子提供了机械稳定的平台。通过 BET 表面积分析发现，与原始 PET 电纺纳米纤维相比，用功能纳米材料增强的纳米纤维具有可控的孔隙几何形状，这导致了更高的金属离子吸收率。我们强调了基于机械稳定性电纺聚合物纳米纤维膜的缓解策略的重要性，以满足饮用水的巨大需求，实现环境的长期可持续性。通过加入碳基纳米填料实现纳米纤维的功能升级。通过形态优化控制孔隙率，以去除污染物。

期刊介绍： For more than 30 years, Polymer Engineering & Science has been one of the most highly regarded journals in the field, serving as a forum for authors of treatises on the cutting edge of polymer science and technology. The importance of PE&S is underscored by the frequent rate at which its articles are cited, especially by other publications - literally thousand of times a year. Engineers, researchers, technicians, and academicians worldwide are looking to PE&S for the valuable information they need. There are special issues compiled by distinguished guest editors. These contain proceedings of symposia on such diverse topics as polyblends, mechanics of plastics and polymer welding.
