| 摘 要： | 采用固/液界面溶剂溶胀诱导相分离法,对磺化聚苯乙烯(SPS)和表面负载有生物相容性的壳聚糖(CS)的核壳型SPS/CS两种微球进行溶蚀,制备出具有多孔结构的SPS和SPS/CS微球。研究发现,溶剂类型和醇水比是影响多孔聚合物微球形态的主要因素。利用透射电镜(TEM)对多孔微球的结构进行表征,通过紫外可见分光光度计(UV-Vis)测定SPS/CS多孔微球在室温环境下对Cr3+的吸附行为。结果表明,界面溶蚀法可制备出形貌均一的多孔聚合物微球,其对Cr3+吸附量明显优于实心结构的微球。

| Abstract: | Sulfonated Polystyrene（ SPS）microsPheres were used as temPlates and core-shell SPS/CS mi-crosPheres were PrePared by adsorbing chitosan onto the SPS surface via electrostatic interaction between amino and sulfoacid grouPs. Porous structured SPS and SPS/CS microsPheres were PrePared by solvent/nonsolvent induced Phase seParation method. Transmission electron microscoPy（ TEM）was used to ob-serve the microstructure and the Cr3＋ adsorPtion behavior was characterized by UV-Vis at room temPera-ture. The results indicated that the uniform morPhology of the Porous Polymer microsPheres was PrePared by interface dissolution method. And the Porous SPS/CS showed an obviously enhanced maximum adsorP-tive caPacity to Cr3＋. |
