Role of π‐π interactions and chain flexibility in dispersion and dynamic‐mechanical properties of nanocomposites with multiple wall carbon nanotubes

Two polymers of same functional group were used; one with greater chain flexibility, PA 6.6, and the other with two benzene rings in the main chain, PA 6I‐6T (aPA), to evaluate how the structure influences on the nanoparticle dispersion homogeneity and on dynamic‐mechanical properties. In the aPA nanocomposites, good dispersion and homogeneous distribution were observed for all CNT concentrations. However, PA 6.6 nanocomposites showed...
