Open-cell nanocomposite foams of poly(vinylidene fluoride-co-trifluoroethylene) [P(VDF-TrFE)] and multi-walled carbon nanotubes (MWCNTs) were investigated for airborne sound absorption. When MWCNTs were well dispersed in the P(VDF-TrFE) matrix, the degree of crystallinity of the polar phase of the p...
