Abstract In this work, the Pickering emulsion polymerization of styrene (STY) with silica nanoparticles as stabilizers and ammonium persulfate (APS) as initiator, was studied. The effects of several co-aids, considered as modifying agents to vary the compatibility of colloidal silica (Ludox AM) between the polymer interface during the emulsion polymerization, are evaluated. Sodium vinyl benzene sulfonate, 4-vinyl pyridine, poly(ethylene glycol) methyl ether methacrylate (PEGMA), and cetyltrimethylammonium bromide (CTAB) surfactant, are appraised. The obtained emulsions range from bare, hybrid encapsulated and Pickering nanoparticles. The obtained Pickering emulsion formulation requires smaller amounts of co-aids, as compared to the reported recipes from the literature.

混合苯乙烯乳液聚合：裸露、包封和pickering形态

摘要 本研究以二氧化硅纳米粒子为稳定剂，过硫酸铵(APS)为引发剂，对苯乙烯(STY)的Pickering乳液聚合进行了研究。评估了几种共助剂的影响，这些助剂被认为是在乳液聚合过程中改变聚合物界面之间胶体二氧化硅 (Ludox AM) 相容性的改性剂。评价了乙烯基苯磺酸钠、4-乙烯基吡啶、聚（乙二醇）甲基醚甲基丙烯酸酯（PEGMA）和十六烷基三甲基溴化铵（CTAB）表面活性剂。获得的乳液包括裸露、混合包封和皮克林纳米粒子。与文献报道的配方相比，获得的 Pickering 乳液配方需要更少量的助剂。
