Abstract Today, polymer composites are used to store liquid chemicals. Monitoring their structural health is crucial. In this study, conductive nanocomposite-based sensors were designed to monitor acid penetration over time. The sensors were made using blends of epoxy resin and additives, such as polyaniline and carbon nanotube (CNT). It appeared that as the concentration of additives increased, the sensors' response time were shorter. The CNT-based nanocomposites had shown an especially high sensitivity. However, to track the acid penetration over time, polyaniline-based sensors seem more adequate. A simple kinetic model was developed to have a better understanding of sensor behavior.

基于 CNT 和聚苯胺的传感器用于检测聚合物复合材料中的酸渗透

摘要 今天，聚合物复合材料用于储存液体化学品。监测它们的结构健康至关重要。在这项研究中，基于导电纳米复合材料的传感器被设计为随着时间的推移监测酸渗透。这些传感器使用环氧树脂和添加剂的混合物制成，例如聚苯胺和碳纳米管 (CNT)。似乎随着添加剂浓度的增加，传感器的响应时间更短。基于 CNT 的纳米复合材料表现出特别高的灵敏度。然而，随着时间的推移跟踪酸渗透，基于聚苯胺的传感器似乎更合适。开发了一个简单的动力学模型以更好地了解传感器行为。
