Special Issue Information

Dear Colleagues,

Nanocomposites are studied by many researchers due to their potential benefits in improving structural, thermal, electrical, and magnetic material properties. Reinforcing materials such as nanofibers, nanoparticles, nanotubes, and 2D graphene are the most commonly used in such multi-phase material system. The potential applications of such nanocomposites are found in many engineered products. This Special Issue on the “Mechanical Properties of Polymer Nanofiber and Graphene Reinforced Polymer Composites” focuses on both experimental and computational work representing the mechanical behavior of polymer nanocomposites. The role of nano-reinforcing materials in terms of orientation, dispersion, concentration, aspect ratio, size, and fiber/matrix interfacial bonding in fracture behavior and mechanical properties are important in characterizing nanocomposites. Analytical work related to electron microscopy, atomic force microscopy, nano-indenters, Raman spectroscopy, and mechanical testing are extensively used in characterizing the fracture behavior and mechanical properties of nano-composites. Any real-time monitoring systems and nondestructive evaluation techniques such as acoustic emission, imaging, and other devices for characterizing the fracture behavior of nanocomposites are encouraged. Materials processed through traditional methods and 3D printing also play a major role in the mechanical  behavior of composites. Computational work focuses on molecular dynamics simulation, peri-dynamics, finite element methods, analytical tools, and any other computational tools. Technical papers highlighting the above focus areas including other innovative techniques or methodologies are invited for publication in this Special Issue.

Studies of polymer/carbon nanotube (CNT) fibers typically focus on optimizing the overall properties, and the effects of structural variation on these properties are ignored. Thus, we investigated the longitudinal variation in the properties of CNT/polyvinylidene fluoride (CNT/PVDF) fibers prepared by wet spinning a solution of multi-walled nanotubes, PVDF, and dimethylacetamide. To this end, materials for the CNT/PVDF fiber were selected, and a dope solution was prepared using MWNT, PVDF, and dimethylacetamide (DMAc). To consider the process parameters that would affect the performance of the CNT/PVDF fiber during the wet-spinning process using the dope solution, the initial conditions for wet spinning were selected, including bath concentration, bath temperature, drying temperature, and elongation, and the CNT/PVDF fiber was spun under the corresponding conditions. Additionally, three performance stabilization processes were proposed to improve the initial conditions for wet spinning and manufacturing the fiber. Lastly, to confirm the reliability of the CNT/PVDF fiber in all sections, tensile strength, electrical conductivity, and cross-sectional images were analyzed for the 30 m, 60 m, and 90 m sections of the fiber, and the reliability of the wet-spinning process was verified.
