Energy storage and conservation are receiving increased attention due to rising global energy demands. Therefore, the development of materials is crucial. Thermal (TES) systems based on phase change (PCMs) have in prominence over past two decades, not only because their outstanding heat capacities but also superior thermal regulation capability. However, issues such as leakage low conductivity limit applicability a variety settings. Carbon-based graphene its derivatives can be utilized surmount these obstacles. This study examines recent advancements graphene-based composites (PCCs), where nanostructures graphene, oxide (GO), functionalized graphene/GO, aerogel (GA) incorporated into PCMs substantially enhance shape stability that could translated better capacity, durability, temperature response, thus boosting attractiveness for TES systems. In addition, applications PCCs various disciplines, buildings, solar utilization, battery management, discussed summarized.

Polyethylene glycol (PEG) is widely used as phase change materials (PCM) due to their versatile working temperature and high latent heat. However, the low molecular weight of PEG prevents from formation flexible microfibers, common leakage problem associated with solid-liquid PCM further hinders applications in various fields. To address these challenges, polyethylene oxide (PEO) incorporated supporting matrix for PEG, leading a successful electrospinning fibrous mats. Due similar chemical nature both PEO, blended composites show great compatibility produce uniform electrospun fibers. The thermal properties fibers are characterized by DSC TGA, supercooling PEG(1050) component effectively reduced 75-85%. morphology changes before after test analyzed SEM. Tensile DMA tests that presence contributes plasticization effect, improving mechanical thermomechanical strength. ratio PEO(600K):PEG(1050) at 7:3 affords optimal performance good form-stability, least shrinkage, uniformity. These mats have potential areas food packaging, wearable devices, or textiles aid regulation.

Abstract Polyethylene (PE), a highly prevalent non‐biodegradable polymer in the field of plastics, presents waste management issue. To alleviate this issue, bio‐based PE (bio‐PE), derived from renewable resources like corn and sugarcane, offers an environmentally friendly alternative. This review discusses various production methods bio‐PE, including fermentation, gasification, catalytic conversion biomass. Interestingly, bio‐PE volumes market are expanding due to growing environmental concerns regulatory pressures. Additionally, biocomposites using agricultural as filler materials, highlights demand for sustainable alternatives conventional plastics. According previous studies, addition ≈50% defibrillated abaca fibers into matrix compatibilizer, results highest Young's modulus 4.61 5.81 GPa, respectively. These have potential applications automotive, building construction, furniture industries. Moreover, advancement made abiotic biotic degradation is elucidated address their impacts. Finally, paper concludes with insights opportunities, challenges, future perspectives utilization biocomposites. In summary, can contribute cleaner future.
