In this work, an overview on aqueous solutions of polyoxyethylene alkyl ether carboxylic acids is given. Unique properties arise from the combination of the nonionic, temperature-responsive polyoxyethylene block with the weakly ionic, pH-responsive carboxylic acid termination in a single surfactant headgroup. Accordingly, this class of surfactant finds broad application across very different sectors. Despite their large use on an industrial and a technical scale, the literature lacks a systematic and detailed characterization of their physico-chemical properties which is provided herein. In addition, a comprehensive overview is given of their self-assembly and interfacial behavior, of their use as colloidal building blocks and for large-scale applications.

在这项工作中，给出了聚氧乙烯烷基醚羧酸水溶液的概述。单一表面活性剂头基团中非离子，温度响应性聚氧乙烯嵌段与弱离子，PH响应性羧酸端基的结合产生了独特的性能。因此，这类表面活性剂在非常不同的领域中得到了广泛的应用。尽管它们在工业和技术规模上被广泛使用，但是文献缺乏本文提供的它们的理化性质的系统和详细的表征。此外，还对它们的自组装和界面行为，用作胶体构造块和用于大规模应用进行了全面概述。
