石油和石油副产品泄漏到水体中会对水生生物和人类造成严重损害沿着造成巨大的经济损失。使用现有技术的吸附剂材料从油-水混合物中分离油的有效方法目前正在进行中，包括简单合成高分离效率、轻质和耐用的复合材料。在这项工作中，我们报告了一种基于多层氟化石墨烯（FG）纳米片支撑铜基金属有机框架（HKUST-1）的疏水/超亲油纳米多孔复合材料的室温合成，通过“溶液辅助自组装路线”。采用接触角测定仪测定了复合材料的溶剂接触角和表面自由能，系统地表征了复合材料的形成和化学连接性。探索了FG-HKUST-1材料的自清洁和溶液可加工性，用于吸附油和有机物，然后从油水混合物中回收油。此外，FG-HKUST-1复合海绵在恶劣条件下显示出优异的化学和物理稳定性。
The spills of oils and petroleum byproducts into water bodies cause severe damage to aquatic species and humans along with massive loss to economy. Efficient methods using state of art sorbent materials to separate oil from oil–water mixtures are currently underway comprising simple synthesis of high separation efficiency, lightweight, and durable composites. In this work, we report a room temperature synthesis of hydrophobic/superoleophilic nanoporous composites based on multilayered fluorinated graphene (FG) nanosheet supported copper-based metal organic framework (HKUST-1) by a “solution assisted self-assembly route”. The formation and chemical connectivity of FG-HKUST-1 composite was systematically characterized followed by measuring solvent contact angles and surface free energy by contact angle goniometer. The self-cleaning and solution processability of the FG-HKUST-1 materials was explored toward oil and organics sorption followed by oil recovery from oil–water mixtures. Furthermore, FG-HKUST-1 composite sponges display excellent chemical and physical stabilities under harsh conditions.
