Surface engineering, especially surface hydrophilicity and active binding sites are crucial for porous polymers in the removal of fluoride ions from water. Herein, a novel P(DVB-AMPS) copolymer with tailored surface engineering was designed through a one-step polymerization method by incorporating diethylene-benzene (DVB) and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS). AMPS endows abundant active binding sites and provides P(DVB-AMPS) with both hydrophilicity and affinity for fluoride ions, while the monomer DVB acting as a crosslinker, facilitating pore generating. The surface hydrophilicity of P(DVB-AMPS) could be easily tuned by increasing the amounts of AMPS with the contact angle decreased from 126° (PDVB) to 52°. Furthermore, P(DVB-AMPS) material maintains a large specific surface area of 428 m2 · g[Formula: see text] and preserves its highly porous structure. P(DVB-AMPS) exhibits an efficient adsorption capacity (51.9 mg · g[Formula: see text]) and a rapid adsorption rate (6.83 mg · g[Formula: see text] · min[Formula: see text]), which demonstrates competitive performance compared with previous reports. Importantly, the material possesses highly selective adsorption toward fluoride. The excellent adsorption performance of P(DVB-AMPS) is attributed to the high porosity, improved surface hydrophilicity and active binding sites. This work not only provides a new strategy for designing high-performance adsorbents but also offers a novel polymer material for the efficient capture of fluoride ions from water.
