Lightweight polymer insulators are an important and sustainable alternative to ceramic materials for power distribution to towns and cities across the globe. They are less expensive and require less energy to manufacture, and may offer longer and more stable service in harsh environments such as hot climates where the polymers experience temperatures up to 55 degrees, winter areas where de-icing salts accumulate on polymer surfaces, and coastal environments where contamination by algae is a serious concern. It is important to understand how the polymer materials stand up to these conditions, in particular how such environmental exposure may compromise the ability of the material to prevent the ingress of water. In all of these cases, testing must be done under simultaneous electrical stress, to best reproduce the 40,000-volt application in use. This proposal seeks to study the fundamental physical chemical properties of polymer insulator surfaces under elevated temperature and high voltage, and subsequently characterizes the ability of freshwater and saltwater algae to colonize the surface. At the same time, this project provides many opportunities for training the next generation of scientists and engineers in advanced materials characterization methods.

轻质聚合物绝缘子是地球仪城镇配电中陶瓷材料的重要和可持续替代品。它们更便宜，制造所需的能量更少，并且可以在恶劣环境中提供更长和更稳定的服务，例如聚合物经历高达55度的温度的炎热气候，除冰盐在聚合物表面上积累的冬季地区，以及藻类污染是严重问题的沿海环境。重要的是要了解聚合物材料如何耐受这些条件，特别是这种环境暴露如何可能损害材料防止水进入的能力。在所有这些情况下，测试必须在同时的电应力下进行，以最好地再现使用中的40，000伏应用。该提案旨在研究高温高压下聚合物绝缘子表面的基本物理化学性质，并随后表征淡水和咸水藻类在表面定居的能力。与此同时，该项目为培训下一代科学家和工程师提供了许多先进材料表征方法的机会。
