我们介绍了我们对能够充当刺激响应膜的聚电解质聚合物刷的研究。我们首先详细介绍了使用 ATRP 以“嫁接”策略合成聚丙烯酸聚合物刷。值得注意的是，我们采用了无化学物质的脱保护步骤，应该使锚定酯基团保持完整。我们已经演示了这些聚合物组件如何响应 pH 值和电解质浓度等刺激。我们使用聚丙烯酸聚合物刷来合成金属纳米颗粒并回顾了这项工作。我们使用 XPS、ATR-FTIR 和 AFM 光谱来显示聚合物刷内银和钯纳米颗粒的存在。最后，我们报告了AB二嵌段聚两性电解质聚合物刷的合成，它代表了聚电解质聚合物刷的延伸。
We present an account of our research into polyelectrolyte polymer brushes that are capable of acting as stimuli-responsive films. We first detail the synthesis of poly(acrylic acid) polymer brushes using ATRP in a "grafting from" strategy. Significantly, we employed a chemical-free deprotection step that should leave the anchoring ester groups intact. We have demonstrated how these polymer assemblies respond to stimuli such as pH and electrolyte concentration. We have used poly(acrylic acid) polymer brushes for the synthesis of metallic nanoparticles and review this work. We have used XPS, ATR-FTIR, and AFM spectroscopy to show the presence of silver and palladium nanoparticles within polymer brushes. Finally, we report the synthesis of AB diblock polyampholyte polymer brushes that represent an extension of polyelectrolyte polymer brushes.
