The physical properties of nanocomposites may be improved by addition low content carbon nanotubes (CNTs). In contrast, for higher concentrations CNTs, the degraded owing to agglomeration. recent years, due increasing applications many efforts have been performed overcome agglomerates, achieving real potential CNTs in improving performance nanocomposites. To this end, review paper, impact agglomeration on various CNTs/polymer was investigated. Besides, present work provides a effective factors that lead conventional and novel strategies adopted control phenomenon are also presented. findings revealed dense agglomerates negatively affect all It observed elastic modulus tensile strength epoxy-based can around 25 35% when weight fraction is increased from 0.5 1.0 wt.%. case fracture toughness, it reported adding 0.1, 0.2, 0.3 0.4 wt.% an nanocomposites, toughness enhances 17, 24, 30, 4%, respectively. addition, 50% reduction thermal conductivity nanocomposite happened formation concluded presence coefficient friction polymer-based increases 0.027 0.034. slight improve electrical certain extent. some expensive proposed adversely structure, not so prevent occurrence agglomeration, or applicable high-volume production However, implementation such as 3D porous structures could challenge significantly.

The addition of low-loading content nanofillers may improve the material properties polymer-based nanocomposites. This improvement directly corresponds to density well-dispersed in matrix. However, for higher nanofiller loadings, nanocomposites' not only be improved but also degraded due agglomeration. complex phenomenon, where tend form agglomerates with enhancement volume fraction, poses significant challenges materials science and nanotechnology. It has been proven that agglomerations hinder performance nanocomposites thwart unique most aspects. Graphene, one used nanofillers, plays a remarkable role Therefore, key focus current review is provide insight into impact agglomeration on various such as tensile, flexural, fracture, fatigue, thermal, electrical, barrier characteristics polymer reinforced by graphene-based structures. A comprehensive factors leading graphene was presented. concluded could developing nanocomposites, controlling were discussed depth, highlighting issue's complexity.
