Abstract
Polystyrene (PS)/multi-walled carbon nanotubes (CNT) nanocomposites have been prepared through melt mixing processingaiming at obtaining a uniform and homogeneous dispersion of the used nanoparticles within the polymeric matrix. Optical and scanningelectron microscopy has been employed to determine the dispersion and distribution of CNTs at different length scales. Furthermore, thelinear viscoelastic behavior of formulated nanocomposites has been deeply investigated. As a result of CNTs added, the nanocompositesexperience a transition from liquid-like to solid-like rheological behavior, and a disappearance of relaxation processes at low frequency can benoticed. By plotting G’ versus CNTs loading and fitting with a power-law function, the rheological threshold of PS-based nanocomposites hasbeen calculated. Moreover, the mechanical behavior of nanocomposites has been investigated and related to the formed CNTs network withinpolymer matrix.
