Abstract

The development of efficient water purification technologies is a critical research focus driven by the crucial role of clean water sources for ecological sustainability. This study explores the strategic incorporation of nanoparticles within polyvinylidene fluoride (PVDF) membranes as a promising approach to enhance membrane performance for wastewater remediation. PVDF membranes containing varying ratios of graphene (GR) and titanium dioxide (TiO2) nanocomposites were fabricated via phase inversion method. Characterization techniques including XRD, FTIR, and FESEM‐EDX revealed that the 80% GR nanocomposite membrane exhibited desirable structural and functional properties with pronounced sponge‐like morphology and homogenous nanoparticle distribution. Fourier‐transform infrared spectroscopy and x‐ray diffraction analysis confirmed the 80% GR membrane retained PVDF crystallinity while uniquely eliminating TiO2 crystallinity. Subsequently, performance testing demonstrated the 80% GR nanocomposite membrane had the highest water flux and methylene blue dye rejection rates compared to other ratios and the pristine PVDF membrane. Both fabricated membranes exhibited sufficient reusability and antifouling properties. However, 80% GR ratio exhibited superior antifouling properties, indicating its potential as an optimal material for improving membrane hydrophilicity and overall water purification technologies. These findings underscore the strategic utility of GR‐TiO2 nanocomposites for enhancing PVDF membrane performance in sustainable wastewater treatment applications.

聚偏二氟乙烯纳米复合膜中的二氧化钛/石墨烯对提高亚甲基蓝染料去除率、防污性能和重复使用性的影响

由于清洁水源对生态可持续性的关键作用，开发高效的水净化技术成为一项重要的研究重点。本研究探讨了在聚偏二氟乙烯（PVDF）膜中策略性地加入纳米粒子，作为提高废水修复膜性能的一种可行方法。通过相反转法制造了含有不同比例石墨烯（GR）和二氧化钛（TiO2）纳米复合材料的聚偏二氟乙烯（PVDF）膜。XRD、FTIR 和 FESEM-EDX 等表征技术表明，80% 的 GR 纳米复合膜具有理想的结构和功能特性，具有明显的海绵状形态和均匀的纳米粒子分布。傅立叶变换红外光谱和 X 射线衍射分析证实，80% GR 膜保留了 PVDF 结晶性，同时独特地消除了 TiO2 结晶性。随后的性能测试表明，与其他比率和原始 PVDF 膜相比，80% GR 纳米复合膜具有最高的水通量和亚甲基蓝染料去除率。两种膜都具有足够的重复使用性和防污性能。然而，80% 的 GR 比率显示出更优越的防污性能，表明它有潜力成为改善膜亲水性和整体水净化技术的最佳材料。这些发现强调了 GR-TiO2 纳米复合材料在可持续废水处理应用中提高 PVDF 膜性能的战略用途。
