In this article, polypropylene (PP)/clay/carbon nanotube (CNT) composites were prepared via a solution blending method. Sound transmission loss (STL), determined with an impedance tube, was used to characterize their soundproofing properties. The STL for the PP/4.8 wt % clay/0.5 wt % CNT composite was about 15–21 dB higher than that for pure PP at high frequencies (3200–6400 Hz) and about 8–14 dB higher at low frequencies (580–620 Hz). X‐ray diffraction (XRD) and transmission electron microscopy (TEM) were used to study the crystallinity and the microstructure. A synergistic effect on the STL was established between the structure of the homogeneous dispersion and strong interfacial adhesion. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
