Poly(ethylene glycol dimethacrylate-co-acrylic acid) (poly(EGDMA-co-AA)) small microspheres were effectively self-assembled on poly(ethylene glycol dimethacrylate-co-4-vinylpyridine) (poly(EGDMA-co-VPy)) surfaces to form a core-corona structure with a raspberry-like polymer composite by a hydrogen interaction mechanism through an affinity complex between the carboxylic acid group and pyridine group. The control of coverage of the poly(EGDMA-co-AA) corona on the surface of poly(EGDMA-co-VPy) was studied in detail via adjustment of the nature of the mass ratio between the core and corona. The effects of the pH and solvent used on the morphology of the self-assembled core-corona polymer composites were investigated. The nature of the interaction between the core and corona polymer particles was identified as hydrogen bonding with FT-IR spectroscopy.
聚（乙二醇二甲基丙烯酸酯 - 共 - 丙烯酸）（聚（EGDMA - 共 - AA））小微球通过羧酸基团和吡啶基团之间的亲和络合物，经氢相互作用机制有效地自组装在聚（乙二醇二甲基丙烯酸酯 - 共 - 4 - 乙烯基吡啶）（聚（EGDMA - 共 - VPy））表面上，形成具有覆盆子状聚合物复合材料的核 - 壳结构。通过调节核与壳之间的质量比性质，详细研究了聚（EGDMA - 共 - AA）壳在聚（EGDMA - 共 - VPy）表面上的覆盖控制。研究了pH值和所用溶剂对自组装核 - 壳聚合物复合材料形态的影响。通过傅里叶变换红外光谱法确定核与壳聚合物颗粒之间相互作用的性质为氢键。
