Water pollution has become an urgent issue for our modern society, and it is highly desirable to rapidly deal with the water pollution without secondary pollution. In this paper, we have prepared a reduced graphene oxide (RGO) wrapped sponge with superhydrophobicity and mechanically flexibility via a facile low-temperature thermal treatment method under a reducing atmosphere. The skeleton of this sponge is completely covered with RGO layers which are closely linked to the skeleton. This sponge has an abundant pore structure, high selectivity, good recyclability, low cost, and outstanding adsorption capacity for floating oil or heavy oil underwater. In addition, this sponge can maintain excellent adsorption performance for various oils and organic solvents over 50 cycles by squeezing, and exhibits extremely high separation efficiencies, up to 6 × 106 and 3.6 × 106 L·m−3·h−1 in non-turbulent and turbulent water/oil systems, respectively. This superhydrophobic adsorbent with attractive properties may find various applications, especially in large-scale removal of organic contaminants and oil spill cleanup.

膜接触破乳——用于油包水乳液分离的超疏水ZIF-8@rGO膜 Article

水-油界面不平衡是实现油包水乳液破乳的关键。传统膜通常是依赖较高的跨膜压力破坏界面平衡而实现破乳。本文提出了可自然、快速地破坏水-油界面平衡的“接触破乳”的概念,开发了一种对有机组分具有高通量的新型破乳分离膜。具体制备过程分为两步,首先通过真空辅助抽滤法在聚四氟乙烯(PTFE)基底上组装ZIF-8@rGO微球(ZGS)层,再采用聚二甲基硅氧烷(PDMS)交联溶液进行固定化处理。由于ZGS表面为微纳米阶层结构,所制备的ZIF-8@rGO@PDMS/PTFE(ZGPP)膜表面展现出超疏水性特性,当表面活性剂稳定的油包水乳液接触到膜表面时,微纳结构的超疏水膜表面会引起水-油界面不平衡。ZGPP膜对油包水乳液具有良好的分离破乳性能,在0.15 bar(15 kPa)的低跨膜压力下,分离效率可以达到99.57%,通量可达到2254 L·m‒2·h‒1,且对于表面活性剂稳定的纳米级甲苯水乳液(平均液滴尺寸为57 nm)的体系也可以实现破乳分离。“接触破乳”概念的提出有望为开发新一代油包水乳液分离的破乳膜提供新的思路。

将聚乙烯吡咯烷酮(PVP)与聚(乙烯-乙烯醇)(EVAL)共混,采用浸没沉淀法制备了PVP/EVAL共混膜,并用于油水乳液分离过程。通过全反射红外光谱、扫描电子显微镜、拉伸试验、接触角测试等对膜的组成、结构形态、机械性能、亲水性进行了表征,并研究了PVP添加量对共混膜油水分离性能的影响。结果表明:添加PVP能较显著地改变EVAL膜的结构,且共混膜的机械强度和亲水性得到明显改善,当PVP添加量为10 wt%(PVP在铸膜液中的质量分数)时,其拉伸强度和断裂伸长率分别为纯EVAL膜的1.88 倍和1.34 倍。当PVP 添加量为4 wt%时,油水分离稳定通量为纯EVAL 膜的1.81 倍,截留率为92.2 %,比纯EVAL 膜略高。PVP 添加量为10 wt%的PVP/EVAL 共混膜清洗后通量恢复率由纯EVAL 膜的51 %增至77.98 %。
