Special Issue Information

Dear Colleagues,

Polymeric materials are vital across sectors due to their versatile properties; however, aging leads to performance degradation. Durability hinges on various factors: material attributes, manufacturing conditions, aging types, environmental influences, and usage patterns. The scientific focus is on understanding polymer aging and durability, prompting the development of reliable methods for long-term performance prediction.

This Special Issue serves as a forum to discuss achievements and challenges in polymer aging and durability, examining property alterations and strategies to bolster long-term performance. Given their ubiquitous applications, comprehending the enduring behavior of polymeric materials, including composites and nano-composites, is paramount. By fostering interdisciplinary dialogue and compiling cutting-edge research, this Special Issue aims to advance understanding of polymer aging behavior and shape future advancements in this critical field.

Abnormal heating will reduce the insulation performance of composite insulators or even cause insulator fracture, and the abnormal heating phenomenon is more serious under high-humidity conditions. Therefore, in this paper, the voltage withstand test of abnormal heating composite insulators caused by aging and damp sheath, decay-like core rod, and contamination were carried out under different ambient humidity. The heating and discharge of composite insulators were observed by infrared thermal imager and ultraviolet imager, and its temperature characteristics were analyzed from the aspects of heating range, heating shape, and temperature difference. In addition, in order to study the abnormal heating mechanism of composite insulators, the micro-morphology, chemical groups and dielectric properties of the silicon rubber of composite insulators with aging and damp sheath and the decay-like core rod were also measured. It is found that the temperature characteristics of the three types of abnormal heating composite insulators are different, and the temperature difference increases with the increase of humidity. The deterioration of silicone rubber and core rod material is the internal reason for the abnormal heating of composite insulators, and high-humidity conditions will exacerbate the heating phenomenon.
