Special Issue Information

Dear Colleagues,

In the quest for sustainable and efficient energy solutions, carbon nanocomposites have emerged as a promising frontier. This Special Issue, titled "Carbon Nanocomposites for Energy", aims to highlight the latest advancements and breakthroughs in the development and application of carbon nanocomposites within the energy sector. Carbon nanomaterials, such as carbon nanotubes and graphene, possess remarkable mechanical strength, electrical conductivity, and thermal stability. When combined with other materials to form nanocomposites, these properties can be synergistically enhanced, leading to innovative materials with tailored characteristics for various energy-related applications. From energy storage systems like batteries and supercapacitors to energy conversion devices such as fuel cells and photovoltaics, carbon nanocomposites are playing a pivotal role in improving performance, efficiency, and durability.

This Special Issue will bring together contributions from leading researchers and experts in the field, showcasing cutting-edge research on the synthesis, characterization, and application of carbon nanocomposites for energy. We invite submissions that explore novel synthesis methods for carbon nanocomposites, detailed studies on their microstructures and properties, and practical demonstrations of their use in energy devices. The goal is to provide a comprehensive overview of the current state of the art, identify key challenges, and outline future directions for the development of carbon nanocomposites in the energy domain. By fostering collaboration and knowledge sharing among researchers, we hope to accelerate the translation of these promising materials from the laboratory to real-world energy applications.

We believe that the insights and findings presented in this Special Issue will significantly contribute to the ongoing efforts to address global energy challenges. Carbon nanocomposites have the potential to revolutionize energy technologies, making them more efficient, sustainable, and accessible. As Guest Editors, we are excited to curate this collection of high-quality research or review manuscripts and look forward to the innovative ideas and solutions that will be shared. We extend our sincere thanks to all the authors, reviewers, and readers who will be part of this Special Issue, and we eagerly anticipate the impact that this research will have on the future of energy.

At present, composite phase change materials are widely studied for battery thermal management. However, to ensure the battery’s thermal safety, it is necessary not only to control the temperature during regular operation, but also to prevent sudden thermal runaway. This basic function depends on the flame-retardant properties of the composite phase change materials. In this study, a hexagonal double-layer hollow nanocage S2 with defect orientation was prepared and combined with carbon nanotubes (PNT) derived from polypyrrole (PPy) tubes to form a high adsorption mixture. Multifunctional composite phase change material PNT/S2@PEG/TEP was prepared by adsorbing and coating polyethylene glycol 8000 (PEG-8000) and triethyl phosphate (TEP) with microfibrillated cellulose nanofibers (CNF) as the skeleton. The characterization shows that its thermal conductivity is 0.65 W/m·K and its phase transition enthalpy is 146.1 J/g, demonstrating its excellent thermal regulation. Microcalorimetric testing (MCC) confirmed its flame-retardant ability, attributed to the strong adsorption of PNT/S2 on PEG-8000 and TEP, the improvement in PNT’s thermal conductivity, and the contribution of CNF to flexibility. This composite phase change material, with excellent comprehensive properties, has broad application prospects in thermal safety for electronic equipment, significantly expanding its practical scope.

The rapid development of deep-space exploration and crewed missions makes efficient, lightweight, and low–secondary-radiation γ-ray protection in complex cosmic fields a critical materials challenge. Current studies still struggle to simultaneously balance attenuation efficiency, areal density and thickness, flexibility, and shielding against secondary γ rays. Compared with existing reviews that mainly focus on single matrices (especially polymers) or medical lead-based protection, this work targets γ-ray shielding under deep-space and mixed radiation environments, emphasizing multiscale structural designs (multilayer/gradient architectures, micro/nanofiller synergy, and fiber networks) for suppressing secondary γ-rays and outlining composition–structure–morphology–coupled strategies for flexible, wearable, lead-free shields. Recycling and sustainability remain key bottlenecks for practical deployment. Accordingly, this review also summarizes representative Monte Carlo simulation tools and their integration with experiments, and proposes directions for element selection, structural design, and green manufacturing to build design rules and a scale-up roadmap for next-generation lead-free γ-shielding wearables.
