Abstract Superhydrophobic polymeric foams, with good thermal stability and high‐recycling capacity to remove oil from oily wastewater, are highly desirable for current oily wastewater purification. Herein, poly (styrene‐acrylic acid 2,2,3,4,4,4‐hexafluoro‐butyl ester‐divinylbenzene) foam with porosity as high as 99.27% has been prepared through high‐internal phase emulsions. Therein, poly (cyclotriphosphazene‐co‐4,4′‐sulfonyldiphenol) microspheres, and Span80 act as co‐emulsifier to stabilize the emulsion system. The as‐prepared foams exhibited super hydrophobicity with a water contact angle of 150.3° and thermal stability. Additionally, the oil adsorption capacity of the porous material could reach up to 25.6–53.4 times its mass with accessible and high‐recycling capacity. These aforementioned outstanding properties make our superhydrophobic foam hold potential applications in oil/water separation.
