Abstract
Carbon nanotubes exhibit excellent mechanical properties and hold immense promise for diverse applications. Based on the first nature principle, we investigate the mechanical properties, thermoelectric properties, and energy absorption behavior of the three-dimensional carbon cage thermoelectric material Schwarzites Cn under uniaxial tensile and compressive loading. Our investigation unveils that Schwarzites Cn possess a robust compressive strain threshold, enduring deformation by more than 50%. The large pore structure and multiple ring defects of Schwarzites result in a maximum Young’s modulus (Schwarzites C11) of 91.01 Gpa. The specific energy absorption (SEA) values indicate that Schwarzites Cn can be used as a good energy-absorbing material, with an SEA of 55.89 MJ/kg for Schwarzites C6 at 50% strain in uniaxial compression. At 300 K, Schwarzites C8 with the highest zT (4.5) increases its zT to 4.83 at 5% tensile strain, an increase of 7.3%. The maximum increase in zT is observed in Schwarzites C9, from 0.249 to 0.34, with an increase of 36.5%. This study opens up ideas for the design and application of outstanding mechanical performance carbon materials by deriving three-dimensional carbon cage structures from carbon nanotubes.
期刊介绍:
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
