This contribution reports a novel type of biobased, porous, functional material [poly(high internal phase emulsions), polyHIPEs] prepared from vanillin and laurinol derivatives. The polyHIPEs demonstrate high porosity (90%), low density (0.0935 g/cm(3)), and high specific surface area (38.6 m(2)/g). Owing to the multilevel pore structures (cell, window, and skeleton pores) and the chemical compositions, the polyHIPEs demonstrate suprahydrophobicity, with a water contact angle exceeding 160 degrees, and excellent lipophilicity. The polyHIPEs are further explored as an oil adsorbent. The oil adsorption capacity increases upon increasing the water-oil ratio in the recipe for forming HIPEs and increases up to 40.9 g/g toward chloroform. The recycling use experiments prove that the materials' oil adsorption ability can be well-maintained at least 10 times. The materials also demonstrate rapid oil adsorption capability. The polyHIPEs' advantages, i.e., being derived from biomass and showing high oil-adsorption capacity and satisfactory recycling usability, endow them with promising potential as sustainable oil adsorbents.
