ABSTRACTSingle-walled carbon nanotubes (SWNTs) have exceptional mechanical and functional properties. Many researchers consider SWNTs as the most promising reinforcement for realizing the optimal structural and multifunctional potential of the next generation of high performance nanocomposites. However, due to poor dispersion, weak interfacial bonding and deficient tube orientation, current nanotube-based nanocomposites fail to realize their anticipated properties. A new approach was developed by the authors to use preformed nanotube tube networks (called buckypapers) and a resin infiltration method for producing bulk polymeric nanocomposites with controlled nanostructure and high tube loading. Desired tube alignment in nanocomposites can be achieved by using magnetically aligned carbon nanotube buckypapers, in which SWNTs will tend to align along the direction of applied magnetic field. The mechanical properties of the resultant nanocomposites have been tested. The storage modulus of the magnetically aligned nanocomposites is as high as 47 GPa, which is one of the highest reported values of nanotube-reinforced composites.In this research, we investigated the influences of tube dispersion, loading and orientation on the mechanical properties of SWNT-reinforced composites. Random and aligned discontinuous reinforcement models of composites were applied to predict the tensile moduli of both individually dispersed SWNT-based and SWNT rope-based nanocomposites. The nanostructural parameters used in the calculation models were determined based on our experimental observations. Comparisons between theoretical estimates and experimental results have shown that the formation of SWNT ropes in the composites has a significant influence on the mechanical properties. The experimental results of the both random and aligned SWNT rope composites are in good agreement with the theoretical predictions.

Advancements in polymer/nanoclay nanocomposites have supported the development of distinctive preparation strategies and characteristic features. High-performance polymer/nanoclay nanocomposites have applications in aerospace, automotive, construction, environmental, and biomedicine. To further improve polymer/nanoclay nanocomposite performance, nanoclay nanobifillers have been considered. In this regard, nano-sized carbon allotropes are potential contenders to form nanoclay nanobifillers. This article presents a detailed and state-of-the-art review on polymer/nanoclay nanobifiller nanocomposites. The primary focus of this pioneering effort is to deliver an up-to-date overview on polymer/nanoclay nanobifiller nanocomposites along with their categorization, fabrication, properties, and uses. Nanoclay nanobifiller designs using carbon nanotube, graphene, and fullerene are considered. Consequently, ensuing nanocomposite categories are discussed including polymer/nanoclay-carbon nanotube, polymer/nanoclay-graphene, and polymer/nanoclay-fullerene nanocomposites. The dispersion properties and alignment of nanoclay nanobifiller in polymeric nanocomposites have been investigated. Enhancing the interfacial bonding strength between matrix and nanoclay nanobifiller enhances the resulting nanocomposite physical properties. Application areas for polymer/nanoclay nanobifiller nanocomposites include supercapacitors, non-flammable materials, and self-healing materials. The discussion also highlights potential future directions for this emerging research field. Forthcoming advancements in polymer/nanoclay nanobifiller nanocomposites must focus the intensive design control, nanobifiller functionality, new processing techniques, superior dispersion, and enhanced features to further broaden the application prospects of these materials.

Efforts in the field of polymeric nanocomposites reinforced by carbon nanotubes are presented in the literature from many years. The discussed problems are connected with the characterization of nanocomposites and the modeling of elastic and fracture behavior at the nanoscale. The experimental investigations and the theoretical modeling are conducted simultaneously. The theoretical approaches try to elucidate the experimental observations. In the present paper a brief overview of the analytical and numerical modeling of polymeric nanocomposites reinforced with carbon nanotubes is presented. The attention is mainly focused on the molecular dynamic models, the continuum mechanics approaches and finally the multi-scale models are discussed. The good and wrong sides of the models are pinpointed. Also a comparison between values of Young's modulus of carbon nanotube/polymer nanocomposites for various methods is presented.
