Herein, novel hyperbranched polyamidoamine guanidinium salts (GS-h-PAMAM) and two cationic acrylamide copolymers P(AM-DAC-ABSM) and P(AM-DAC-AMTU) were successfully prepared. Then, self-assembly supramolecular systems were synthesized by directly mixing GS-h-PAMAM with copolymers in aqueous solution, and the mechanism of the self-assembly process was speculated. FT-IR, NMR, and SEM were used for structural confirmation. Furthermore, the excellent solution properties revealed that the supramolecular systems had potential application in clay hydration inhibitors. More importantly, utilizing functionalized hyperbranched polyamidoamine in the synthesis self-assembly supramolecular systems was an effective strategy for expanding their application fields and developing new functional materials, providing a powerful reference for the next study.
在此，成功制备了新型超支化聚酰胺胺胍盐（GS-h-PAMAM）以及两种阳离子丙烯酰胺共聚物P(AM-DAC-ABSM)和P(AM-DAC-AMTU)。然后，通过在水溶液中将GS-h-PAMAM与共聚物直接混合合成了自组装超分子体系，并推测了自组装过程的机理。利用傅里叶变换红外光谱（FT-IR）、核磁共振（NMR）和扫描电子显微镜（SEM）进行结构确认。此外，优异的溶液性能表明该超分子体系在粘土水化抑制剂方面具有潜在应用。更重要的是，在合成自组装超分子体系中利用功能化超支化聚酰胺胺是拓展其应用领域和开发新型功能材料的有效策略，为后续研究提供了有力参考。
