Highly efficient oil/water separation and trace organic contaminants removal based on superhydrophobic conjugated microporous polymer coated devices

•Two kinds of conjugated microporous polymers coated superhydrophobic devices were first reported.•The polymer coated stainless steel mesh shows highly oil/water separation efficiency.•Large-scale removing of organic pollution can be realized by polymer-coated sponge.•The trace residual and solved aromatic pollutions can be removed by polymer-coated sponge.

Superhydrophobic iron(III) porphyrin-based conjugated microporous polymers (CMPs) are successfully coated on both stainless steel mesh and sponge framework, which are well utilized in separating oil and trace organic contaminants from water for the first time. Due to the superhydrophobic character of the material, the CMP-coated stainless steel and sponge both exhibit high oil/water separation efficiency through filtration and adsorption process, respectively. Furthermore, coated sponges can remove not only the large-scale organic solvents but also the trace organic contaminants from water, which make it an excellent candidate for applications of oil/water separation and water purification.
