 Polymer nanocomposites have been gaining popularity due to their improved mechanical, thermal, and electrical properties compared to traditional polymers. However, one of the major challenges faced when producing these composites is the agglomeration of fillers such as multi-layered graphene, MLG, and carbon nanotubes, CNTs. This can be avoided through the use of organic solvents, selection of appropriate dispersion and production methods, and functionalization of the fillers. Additionally, hybrid fillers may also be used to create synergistic effects, which can lead to better dispersion of the fillers. This review paper discusses all of these factors in detail and provides guidance on how to optimize the production of polymer nanocomposites with enhanced properties.
