Dynamic mechanical properties due to incorporation of carboxylated multiwalled carbon nanotubes into three-layer polymer structure, with high damping property, via in situ emulsion polymerization and also blending are studied in detail. Using of storage modulus, loss modulus and damping behavior obtained from the DMA was investigated the manner of carboxylated MWCNTs into and onto the three-layer polymer structure. It was observed that different morphology and topology were formed using these two manufacturing methods. Also, it was observed that dynamic mechanical and damping properties are due to complex and multifunctional parameters such as adhesion, constrained chains, molecular optimum mobility between polymer and nanotubes.
