摘要:
 在单分散聚苯乙烯种子微球合成基础上，通过两步溶胀法以及傅克（Friedel-Crafts）烷基化反应，制备内外贯通的多级孔聚苯乙烯微球，对微球的化学结构、形貌结构、粒径及分布、孔尺寸及分布等进行研究。结果显示，当单体苯乙烯浓度为15%，以乙醇为溶剂时，种子微球具有良好的单分散性，其平均粒径为3.75 μm；SEM结果显示，微球表面粗糙，具有明显孔洞结构；比表面积分析也显示多级孔聚苯乙烯微球富含大孔、介孔和微孔，比表面积达到575.3 m2/g，表明形成内外贯通的多级孔结构；随着对苯乙烯磺酸钠功能单体用量增加，微球表面Zeta电位明显增加。
Abstract:
 In this paper, on the basis of the synthesis of monodisperse polystyrene seed microspheres, through a two-step swelling method and Friedel-Crafts alkylation reaction, multi-porous polystyrene microspheres with internal and external penetration are prepared. The chemical structure, morphological structure, particle size and distribution, pore size and distribution, etc. were studied. The results show that when the monomer styrene concentration is 15% and ethanol is used as the solvent, the seed microspheres have good monodispersity, with an average particle size of 3.75μm; the SEM results show that the microspheres have rough surface and obvious pore structure. The analysis of the specific surface area also showed that the hierarchical porous polystyrene microspheres are rich in macropores, mesopores and micropores, and the specific surface area reaches 575.3 m 2/g, indicating the formation of a hierarchical pore structure with internal and external connections; with the function of sodium p styrene sulfonate With the increase of monomer dosage, the zeta potential on the surface of the microspheres increased significantly.
