Special Issue Information

Dear Colleagues, 

The thermal behaviour of polymers constitutes a cornerstone of polymer science and engineering, as temperature exerts a profound influence on their structural organization, stability, and functional performance. A comprehensive understanding of thermal phenomena—including in relation to glass transition, melting, crystallization, thermal expansion, and degradation—is indispensable for the rational design, processing, and application of polymeric materials across diverse fields such as packaging, electronics, aerospace, and biomedical technologies. Advances in this area not only elucidate fundamental structure–property relationships, but also enable the development of next-generation polymers with tailored functionalities and improved resilience under demanding conditions. Moreover, increasing emphasis on sustainability underscores the importance of investigating thermal stability, recyclability, and degradation pathways, which are central to advancing environmentally responsible materials. In parallel, recent progress in experimental characterization, computational modelling, and multiscale simulations has broadened the scope of thermal studies, offering unprecedented precision in predicting and controlling polymer behaviour.

This Special Issue, ‘Advances in Thermal Behaviour of Polymers’, aims to showcase original research articles and authoritative reviews that capture state-of-the-art developments in this field. Contributions on a wide range of topics are welcome, including innovative thermal analysis methods, modification strategies to enhance thermal performance, polymer nanocomposites, biodegradable systems, and emerging classes of materials engineered for extreme environments.

Polyethylene of Raised Temperature resistance (PE-RT) is a versatile polymer with an enhanced ability to withstand higher temperatures than other standard polyethylene-derived materials. The application scope of PE-RT pipes extends across a broad range of residential and industrial uses. However, the inherent residual stresses developed during the fabrication processes of these pipes pose a significant challenge to their service performance. Moreover, the technical literature on residual stresses in PE-RT pipes is scarce. The investigations presented in this paper address this scientific and technical gap by experimentally quantifying the residual stresses present in different sizes of PE-RT pipes manufactured at the same plant. The slitting method was employed as the primary experimental procedure in these investigations. In addition to establishing experimental processes, this study aims to mitigate residual stresses in PE-RT pipes by investigating their sensitivity to varying annealing temperatures for one selected pipe size. Subsequently, the optimal annealing temperature (115 °C) was applied to the remaining pipe sizes to determine its efficacy in residual stress mitigation. Through the implementation of these procedures, the circumferential residual stresses in PE-RT pipes subjected to annealing at 115 °C were significantly reduced, with a minimum decrease of 78%. Furthermore, the longitudinal residual stresses were substantially diminished, reaching a state of near-complete elimination. Full article

Fe2O3-reinforced PMMA nanocomposites were prepared by melt blending using a twin-screw micro-extruder. Fixed Fe2O3 loading of 2.5 wt.% was employed, and mixing times of 6 and 12 min were used to obtain nanocomposites with different dispersion characteristics. The structural and morphological properties of the samples were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM), while their thermal degradation behavior was evaluated by differential thermal and thermogravimetric analyses (DTA/TG). The activation energies of thermal degradation were calculated using the Kissinger, Takhor, and Augis–Bennett methods. Increasing the mixing time improved nanoparticle dispersion and reduced agglomeration. The addition of Fe2O3 slightly decreased the characteristic degradation temperatures of PMMA, while the activation energy increased for the better-dispersed sample. The results indicate that interfacial interactions and particle dispersion play important roles in the thermal degradation behavior of PMMA/Fe2O3 nanocomposites. Full article
