▎ 摘　　要

NOVELTY - Producing polystyrene/graphene composite porous material comprises (i) dispersing the graphene uniformly in a mixture of styrene, crosslinking agent and emulsifier Span-80 (RTM: Sorbitan monopalmitate-80), and heating; (ii) adding aqueous solution containing persulfate and sulfate into the mixed liquid, stirring at constant speed to obtain high internal phase emulsion in which the graphene particles and the emulsifier Span-80 (RTM: Sorbitan monopalmitate-80) are synergistically stabilized; (iii) carrying out high internal phase emulsion reaction for 0.5-1 hour, transferring into a plastic wide-mouth reaction cup to continue the heat preservation reaction for 24-48 hours, completing the monomer reaction and drying. USE - The material is useful for oil-water separating as adsorbent (claimed). ADVANTAGE - The material has mechanical property, good and uniform pore size, large pore rate, and high absorbing rate.
