微凝胶是膨胀的交联型聚合物胶体颗粒。我们采用非水分散聚合法制备了含有N-乙烯基甲酰胺(NVF)、甲基丙烯酸缩水甘油酯(GMA)和碱稳定交联剂2-(N-乙烯基甲酰胺)乙醚(NVE)的新型水溶胀微凝胶。微凝胶颗粒的核心富含NVF。壳层含有GMA和NVF。为了揭示胺的官能团,使用了碱性水解,将外壳中的NVF基团转化为乙烯胺(VAM),而核心中的大部分NVF保持不变。水解后的微凝胶(H-NVF-GMA-NVE)在低pH值下为阳离子,并具有聚两性行为。NVE的包合具有防止微凝胶表面微相分离和稳定聚两性离子结构以防止在水解过程中过度碎裂的有益效果。这些新的水膨胀核壳微凝胶是用可伸缩的方法制备的,可能会使未来制备功能化的核壳微凝胶和复合材料成为可能。
Microgels are swollen crosslinked polymer colloid particles. We used non-aqueous dispersion polymerisation to prepare new water-swellable microgels containingN-vinylformamide (NVF), glycidylmethacrylate (GMA) and an alkali-stable crosslinker, 2-(N-vinylformamido)ethyl ether (NVE). The microgel particles had a core that was rich in NVF. The shell contained GMA and NVF. In order to expose the amine functionality, alkaline hydrolysis was used, transforming the NVF groups in the shell to vinylamine (VAM) while leaving most NVF in the core untouched. The hydrolysed microgels (H-NVF–GMA–NVE) were cationic at low pH and were shown to have polyampholyte behaviour. Inclusion of NVE had the beneficial effects of preventing microphase separation at the microgel surface and stabilising the polyampholyte structure against excessive fragmentation during hydrolysis. These new water-swellable core–shell microgels were prepared using scalable methods and may enable future preparation of functionalised core–shell microgels and composites.
