摘要

工业过程中的石油泄漏和乳化油包水混合物对地球上的生物构成严重威胁。为了应对这些环境挑战，利用超湿材料有效处理乳化油/水混合物的方法在过去几年中引起了人们的关注。方法制备了一种超疏水金属-有机骨架(MOF)/多面体低聚硅氧烷（POSS）复合材料（AlTz-68-POSS）。然后将其用于修饰三聚氰胺海绵（MS）制备超疏水海绵，AlTz-68-POSS@MS.Significant findingAlTz-68-POSS@MS表现出优异的有机溶剂吸收能力，最高可达129 g/g。此外，它对表面活性剂稳定的油包水乳液（SWOE）表现出了出色的分离性能，在重力驱动条件下实现了极高的分离通量，高达8,670 L m-2 h-1，在外部压力驱动测试中达到1,531,000 L m-2 h-1 bar-1。所有滤液的油纯度均超过99.98 wt%。与许多其他类型的超湿mof改性复合材料相比，AlTz-68-POSS@MS对swes具有优异的助熔剂和分离效率。

Preparation of fluorine-free superwetting metal-organic frameworks/polyhedral oligomeric silsesquioxanes composites for oil absorption and exceedingly high flux emulsion separation

Background

Oil spills and emulsified water-in-oil mixtures from industrial processes pose a serious threat to organisms on earth. To address these environmental challenges, methods utilizing superwetting materials to efficiently treat emulsified oil/water mixtures have drawn noteworthy interest in the past few years.

Method

Herein, we prepared a superhydrophobic metal-organic frameworks (MOF)/polyhedral oligomeric silsesquioxanes (POSS) composite (AlTz-68-POSS). It was then used to modify melamine sponge (MS) to prepare superhydrophobic sponge, AlTz-68-POSS@MS.

Significant finding

AlTz-68-POSS@MS exhibited distinguished organic solvents absorption capacities of up to 129 g/g. Moreover, it demonstrated outstanding separation performance for surfactant-stabilized water-in-oil emulsion (SWOE), achieving exceedingly high separation fluxes of up to 8,670 L m^-2 h^-1 under gravity-driven conditions, and 1,531,000 L m^-2 h^-1 bar^-1 under external pressure-driven tests. Moreover, the oil purity in the all filtrates exceeded 99.98 wt%. In comparison with many other kinds of superwetting MOF-modified composites, the AlTz-68-POSS@MS shows excellent fluxes and superior separation efficiencies for SWOEs.
