In view of the complexity and diversity of multi-state oils, the development of green and low-cost materials with high selectivity to oils has important ecological significance in the polluted water treatment. Herein, a simple method was proposed to develop large-scale production of superhydrophobic sponges (CPMF200 sponges) for high-efficiency oil/water separation under different complex environments. The as-prepared CPMF200 sponges possessed many superior properties, including high roughness, well-developed porosity, good thermal stability, excellent chemical stability, and superhydrophobic properties (water contact angle is 152°), which is conducive to high oil adsorption capacity (up to 70–179 times of its own weight) and oil-water separation. More importantly, the CPMF400 sponge has an excellent photothermal conversion capability to improve the fluidity of high viscosity oil for oil recovery. Based on a simple synthesis method, it exhibits high-efficiency absorption of multi-state oils and excellent oil-water separation performance and strongly proves their application prospects in treating oily wastewater.

鉴于多态油脂的复杂性和多样性，开发绿色、低成本、对油脂具有高选择性的材料在污染水处理中具有重要的生态意义。本文提出了一种简单的方法来大规模生产超疏水海绵（CPMF200海绵），用于不同复杂环境下的高效油水分离。所制备的 CPMF200 海绵具有许多优越的性能，包括高粗糙度、发达的孔隙率、良好的热稳定性、优异的化学稳定性和超疏水性（水接触角为 152°），有利于高吸油能力（高达自重的 70-179 倍）和油水分离。更重要的是，CPMF400海绵具有优异的光热转换能力，可提高高粘度油的流动性，用于采油。它基于简单的合成方法，表现出对多态油的高效吸收和优异的油水分离性能，有力地证明了其在含油废水处理中的应用前景。
