The environmental durability of polymer based composites has always been a critical concern over its short- and long-term performances. The degree of environmental degradation is supposed to have different mechanisms and kinetics at the polymer/reinforcement interfaces in comparison to the bulk polymer matrix. Differential degradation could possibly attribute a stressed state in the material, especially at the interfaces. Present review is focused on the roles of reinforcing CNT on the performance of the polymeric nanocomposites in different in-service environments (the environmental parameters include temperature, moisture, UV light, low earth orbit space environment, electromagnetic waves). It is essential to understand how the addition of CNTs in polymeric material alters the microstructure at micro- and nano-scale, and how these modifications influence the overall macroscopic behaviour, not only in its as fabricated form, but also its continuous alteration with time in the in-service environment. The technological superiority with CNT addition to polymeric materials may be advantageous, but scientific merits are here to be explored critically for a reliable and sustainable interfacial durability and structural integrity in different in-service environmental conditions.
聚合物基复合材料的环境耐久性一直是人们关注的焦点，因为它会影响材料的短期和长期性能。与聚合物基体的整体相比，在聚合物/增强体界面处，环境降解的程度应该具有不同的机制和动力学。差异降解可能会导致材料处于受力状态，尤其是在界面处。本综述主要关注增强 CNT 在不同服役环境下（环境参数包括温度、湿度、紫外光、低地球轨道空间环境、电磁波）对聚合物纳米复合材料性能的作用。了解 CNT 在聚合物材料中的添加如何改变微观和纳米尺度的微观结构，以及这些变化如何影响整体宏观性能，这一点至关重要，不仅要考虑到其初始制造形式，还要考虑到其在服役环境中随时间的持续变化。将 CNT 添加到聚合物材料中具有技术优势，但需要批判性地探索其科学价值，以确保在不同服役环境条件下具有可靠和可持续的界面耐久性和结构完整性。
