Dear Colleagues,

We are delighted to extend an invitation to participate in an upcoming Special Issue of Polymers, a renowned MDPI journal, entitled "Functional Polymers in Energy Conversion, Management, Storage, and Mechanical Energy Harvesting". This Special Issue aims to showcase cutting-edge research on functional polymers and their diverse applications in energy conversion, management, and storage.

The scope of this Special Issue encompasses a wide range of topics related to functional polymers in the energy sector, including but not limited to:

  • Solar energy conversion: emphasizing novel approaches in solar cell technology, interfacial evaporation, and advancements in solar energy harvesting using functional polymers;
  • Mechanical energy harvesting: highlighting advancements in the field of mechanical energy capture, including friction-based nanogenerators and other polymer-based devices for energy harvesting;
  • Functional polymers in LED technology: addressing the role of polymers in light-emitting diodes (LEDs) for energy-efficient lighting solutions;
  • Polymer composite materials for thermal management: exploring innovative polymers and composites for efficient thermal management in electronic devices, aerospace, and MEMS;
  • Energy storage batteries: investigating the development and optimization of energy storage technologies, with a focus on lithium-ion batteries and other promising systems employing functional polymers.

We invite you to contribute original research articles, reviews, and perspectives that delve into the synthesis, characterization, and application of functional polymers in these diverse energy-related areas. This Special Issue aims to foster knowledge exchange, inspire new ideas, and propel advancements in functional polymers and their multifaceted roles in energy fields. The hope is that this Special Issue will enrich the scientific discourse and drive the development of sustainable energy solutions. We look forward to receiving your submissions and thank you for your support.

The catalytic dehydrogenation of NaBH4 for the generation of H2 has a lot of potential as a reliable and achievable approach to make H2, which could be used as a safe and cost-effective energy source in the near future. This work describes the production of unique trimetallic NiCrPd-decorated carbon nanofiber (NiCrPd-decorated CNF) catalysts using electrospinning. The catalysts demonstrated exceptional catalytic activity in generating H2 through NaBH4 dehydrogenation. The catalysts were characterized using SEM, XRD, TEM, and TEM-EDX analyses. NiCrPd-decorated CNF formulations have shown higher catalytic activity in the dehydrogenation of NaBH4 compared with NiCr-decorated CNFs. It is likely that the better catalytic performance is because the three metals in the NiCrPd-decorated CNF structure interact with each other. Furthermore, the NiCrPd-decorated CNFs catalyzed the dehydrogenation of NaBH4 with an activation energy (Ea) of 26.55 KJ/mol. The kinetics studies showed that the reaction is first-order dependent on the dose of NiCrPd-decorated CNFs and zero-order dependent on the concentration of NaBH4. Full article

Pores are common defects generated during fabrication, which restrict the application of carbon/carbon (C/C) composites. To quantitatively understand the effects of pores on mechanical strength, this paper proposes a representative volume element model of unidirectional (UD) C/C composites based on the finite element method. The Hashin criterion and exponential degraded rule are used as the failure initiation and evolution of pyrolytic carbon matrices, respectively. Interfacial zones are characterized using the cohesive constitutive. At the same time, periodic boundary conditions are employed to study transverse tensile, compressive, and shear deformations of UD C/C composites. Predicted results are compared with the experimental results, which shows that the proposed model can effectively simulate the transverse mechanical behaviors of UD C/C composites. Based on this model, the effects of microstructural parameters including porosity, pore locations, the distance between two pores, pore clustering, and pore shapes on the mechanical strength are investigated. The results show that porosity markedly reduces the strength as porosity increases. When the porosity increases from 4.59% to 12.5%, the transverse tensile, compressive, and shear strengths decrease by 35.91%, 37.52%, and 30.76%, respectively. Pore locations, the distance between two pores, and pore clustering have little effect on the shear strength of UD C/C composites. For pore shapes, irregular pores more easily lead to stress concentration and matrix failure, which greatly depresses the bearing capacity of UD C/C composites. Full article
