The widespread occurrence of zwitterionic compounds in nature has incited their frequent use in designing biomimetic materials. Therefore, zwitterionic polymers are a thriving field. A particular interest for this particular polymer class has currently focused on their use in establishing neutral, low-fouling surfaces. After highlighting strategies to prepare model zwitterionic surfaces as well as those that are more suitable for practical purposes relying strongly on radical polymerization methods, we present recent efforts to diversify the structure of the hitherto quite limited variety of zwitterionic monomers and of the derived polymers. We identify key structural variables, consider their influence on essential properties such as overall hydrophilicity and long-term stability, and discuss promising targets for the synthesis of new variants.
两性离子化合物在自然界中的广泛存在促使它们在仿生材料设计中被频繁使用。因此，两性离子聚合物是一个蓬勃发展的领域。目前，对于这类特殊聚合物的一个特别关注点在于它们在构建中性、低污染表面方面的应用。在重点介绍了制备模型两性离子表面的策略以及那些更适用于实际用途（强烈依赖自由基聚合方法）的策略之后，我们展示了近期为使迄今种类相当有限的两性离子单体及其衍生聚合物的结构多样化所做的努力。我们确定了关键的结构变量，考虑了它们对诸如整体亲水性和长期稳定性等基本性质的影响，并讨论了合成新变体的有前景的目标。
