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.

Published: Jan. 1, 2024

Thanks to their intrinsic properties, multifunctionality and unique geometrical features, two-dimensional nanomaterials have been used widely as reinforcements in polymer nanocomposites. The effective mechanical reinforcement of polymers is, however, a multifaceted problem it depends not only on the properties fillers matrix, but also upon number other important parameters. These parameters include processing method, interfacial aspect ratio, defects, orientation, agglomeration volume fraction fillers. In this review, we summarize recent advances nanocomposites from nanofillers with an emphasis mechanisms reinforcement. Model, bulk hybrid are reviewed comprehensively. use Raman photoluminescence spectroscopies is examined light distinctive information they can yield stress transfer at interfaces. It shown that very diverse family 2D includes materials attribute distrinctive features polymeric focus both graphene some most beyond graphene, including boron nitride, molybdenum disulphide, transition metal dichalcogenides, MXenes black phosphorous. first part review evaluate nanoplatelets "model" Next examine how performance these be optimised Finally, combinations or dimensions assessed thoroughly, such lead additive even synergistic effects.
