利用玻璃毛细管构建的微流控装置制备高度单分散水包油（O/W）乳液，以乳液为模板，采用紫外光引发自由基聚合法实现单分散甲基丙烯酸甲酯（MMA）/苯乙烯（St）多孔共聚微球的快速制备。与传统的热聚合法相比，无需复杂装置，操作简单。通过改变乳化剂PGPR的质量分数对微球多孔结构进行精确调控，并对其油吸附性能进行研究。PGPR质量分数为7.5%时的微球的吸附率为5.8 g/g，在油吸附领域具有应用价值。

A glass capillary-based microfluidic device is employed to prepare highly monodisperse oil-in-water (O/W) emulsions.Using monodisperse O/W emulsions as templates,a series of monodisperse MMA/styrene porous copolymer microspheres are fabricated rapidly by UV light-induced free-radical polymerization method.Compared with traditional thermal polymerization methods,this method does not need complex devices and is easy to operate.The microspheres' porous structure is regulated and controlled accurately through changing the mass fraction of emulsifier PGPR and its performance for adsorbing oil is studied.The adsorption capacity of the microspheres for oil can reach 5.8 g·g^-1 when the mass fraction of PGPR in O/W emulsions is 7.5%(w/v).The microspheres will be attractive in oil adsorption field in the future.
