Investigating the mechanical, morphological, and thermal behavior of PA‐6/SAN/MWCNT blends: Application of Taguchi experimental design

Abstract

This work presents the study of morphology, melting and crystallization characteristics, and mechanical properties of the PA‐6/SAN blends reinforced with multiwalled carbon nanotubes (MWCNTs). The Taguchi method was employed to design the experiments based on the three varying parameters (ie, blend composition, nanofiller content, and sequence of blending) to obtain the optimized mechanical properties of the nanocomposites. In addition, localization of nanotubes was studied in terms of thermodynamic and kinetic prospects. It was observed that, due to the preferential tendency for localization of the carbon nanotubes toward the PA‐6 matrix, mixing protocol had an important role in determining the performance of the nanocomposites. Incorporation of an optimum weight percent of the MWCNT provided a good dispersion of the nanotubes and also an appropriate morphology for the blend. According to the analysis based on the Taguchi method, the optimum mixing protocol, blend composition, and MWCNT loading were M2, 80/20, and 0.5 wt%, respectively.

Effect of multi‐walled carbon nano‐tube on mechanical behavior of glass laminate aluminum reinforced epoxy composites

“…26,27 In recent times, the usage of graphene as a nanofiller substitute to CNTs decreased the production costs of composite significantly. [28][29][30] A specific collection of limited literature is available to acknowledge the way in which the matrix can be strengthened or reinforced to transform the forces for the absorption of energy in FMLs. Among the nanofillers, CNTs have successfully established their ability to improve the mechanical properties as well as the energy absorbability of typical composites.…”

Production of Nanocellulose by Enzymatic Treatment for Application in Polymer Composites

“…According to Zanjanijam et al [ 102 ], the increase in the crystallization temperature in composite systems may be caused by a reduction in the size of the filler particles and obtaining a homogeneous dispersion in the polypropylene matrix, which ultimately leads to an improvement in interfacial adhesion between the components. Moreover, Shabani et al [ 103 ] proved that nanoparticles can affect the crystallinity of a polymeric material by changing the speed of growth and nucleation processes, which is explained by the effect of heterogeneous nucleation. For composites with a filler modified with cellulase from Aspergillus sp., an increase in the temperature value by approx.…”
