Special Issue Information

Dear Colleagues,

Nanofiller-reinforced composites have become a research hotspot in the field of materials science in recent years. By dispersing nanofillers (such as carbon nanotubes, graphene, nano-silicon dioxide, etc.) into the matrix, the mechanical, thermal, and electrical properties of the composites can be significantly enhanced. Compared to traditional composites, nanofillers achieve breakthrough optimization of performance at very low addition levels due to their extremely high specific surface areas and unique interface effects. Such materials show broad application prospects in fields such as aerospace, electronic devices, new energy, and buildings.

This Special Issue of Nanomaterials will explore several key themes on nanofiller-reinforced composites, including, but not limited to, their preparation techniques (such as 3D printing and in situ synthesis), functional applications (electromagnetic shielding, low dielectric materials, photocatalysis), mechanical optimization (strengthening and toughening mechanism, heterogeneous structure design), and thermal management (super insulation, high-temperature stability). The objective is to promote technological innovation in preparation, explore multi-functional application scenarios, and facilitate theoretical and performance optimization research. Researchers are encouraged to contribute original research articles or review articles on the preparation, application, theoretical modeling, and simulation methods of nanofiller-reinforced composites.

Graphene, a remarkable two-dimensional material, enhances the mechanical properties of high-entropy alloys as a reinforcing phase. This study investigated the influence of vacancy defects in graphene on the strengthening effect of FeNiCrCoCu high-entropy alloy through molecular dynamics simulations. The findings reveal that vacancy defects diminish graphene’s strength, resulting in its premature failure. In tensile tests, graphene with defects lowers the yield stress of the composite, yet it retains the ability to impede dislocations. Conversely, graphene exhibits a more pronounced strengthening effect during compression. Specifically, when the deletion of C atoms is less than 1%, the impact is negligible; between 1% and 6%, the strengthening effect diminishes; and when it surpasses 6%, the strengthening effect virtually ceases to exist. This research offers a theoretical foundation for optimizing graphene-reinforced composites. Full article
