Effects of CNT loading on cellular structures and sound absorption of PU foams

Efforts have been made to investigate the role of adding carbon nanotubes (CNTs) as the sound energy decaying fillers on the physical and mechanical properties of polyurethane (PU) foam and thus to correlate them with its directly measured sound absorption coefficient. For this aim, the microstructu...
