Polymer-based materials are promising for use in insulators for electrical power lines as an alternative tocurrent glass or ceramic designs. The plastic structures can offer increased electrical resistance, lowermanufacturing and installation cost, and be of lighter weight. However, there is still work to be done in termsof formulating the material so that it can withstand the extreme summer and winter conditions of Canadianclimates. A large challenge in this area is chemical resistance to de-icing agents. To date, testing of somematerials such as silicone and EPDM (ethylene propylene diene monomer) rubbers has been carried out, andsome general findings exist, but it is remains to be understood how the materials respond to weathering undertheir electrical load. In this proposal, a combination of surface-specific spectroscopy, microscopy, andmacroscopic measurements of the hydrophobicity will be carried out. The aim is to identify which materialsperform the best under specific sets of chemical and physical conditions, and to be able to provide somemolecular-level explanation for any observed degradation in material performance. At the same time, thisproject provides many opportunities for training the next generation of scientists in advanced chemicalstructure and materials characterization methods.

聚合物基材料作为当前玻璃或陶瓷设计的替代品，有望用于电力线路的绝缘体。这种塑料结构可以增加电阻，降低制造和安装成本，并且重量更轻。然而，在制定材料方面仍有工作要做，以使其能够经受住加拿大气候的极端夏季和冬季条件。这一领域的一大挑战是对除冰剂的化学抵抗力。到目前为止，已经对有机硅和三元乙丙橡胶等材料进行了测试，并得出了一些一般性的结论，但这些材料在电负荷下对气候变化的响应仍有待了解。在这项提案中，将结合表面特定光谱、显微镜和宏观测量疏水性。其目的是确定哪些材料在特定的化学和物理条件下表现最好，并能够为观察到的材料性能退化提供一些分子水平的解释。同时，该项目为培训下一代科学家先进的化学结构和材料表征方法提供了许多机会。
