“…[12][13][14] In a range of oil absorbing materials, threedimensional (3D) monolithic porous materials are considered as expectative materials for oil absorbing due to their large specific surface area, low density, high porosity and easy recovery. [15][16][17] Commonly used 3D monolithic porous materials mainly include aerogels, [18][19][20] sponges, [21][22][23] and foams. [24][25][26] These materials have interconnected pore structures that can absorb oil via capillary action, and can swell as they absorb oil, allowing the internal voids to absorb more oil.…”

Developing low‐cost and highly efficient hydrophobic absorbents via simple and environmentally friendly method is demanded for oil‐water separation. This paper reports the preparation of hydrophobic absorbents of porous poly(4‐tert‐butylstyrene‐co‐divinylbenzene) (poly(tBS‐co‐DVB)) via high internal phase emulsion (HIPE) template method. The effects of crosslinking degree and internal phase volume fraction on the porous structure and adsorption performance of the absorbents are investigated. As the tBS/DVB molar ratio increases from 1:1 to 4:1, the adsorption performance of poly(tBS‐co‐DVB) toward hexane first increases to a maximum at a molar ratio of 3:1 and then decreases. As the internal phase volume fraction increases, the specific surface area (SSA) and porosity of the poly(tBS‐co‐DVB)s notably increase from 33.06 m2/g and 84.07% to 102.89 m2/g and 92.94%, respectively. When the internal phase fraction is 95 vol%, the obtained poly(tBS‐co‐DVB) foam with a water contact angle of 140° shows an absorbing capacity as high as 70.21 g/g for dichloromethane. After 10 consecutive adsorption‐desorption cycles, the adsorption performance of the poly(tBS‐co‐DVB) foam shows only a slight decrease, indicating an excellent recycling ability. The obtained poly(tBS‐co‐DVB) foams exhibit the advantages of facile preparation, high oil absorption capacity and satisfactory recoverability, which enable them potential as sustainable oil adsorbents.
