Application of Nano Material to Enhance Acoustic Properties.The influence of MWCNT and hybrid (MWCNT/nanoclay) The increase in mechanical properties was highest for 1.5 phr MWCNT with 69% increase in tensile strength. The improvement in properties was correlated to MWCNT dispersion and fillerpolymer interactions, which were confirmed by TEM and FTIR analysis. Hydrocarbon transport coefficients decreased on addition of MWCNT.The impact of different multi-walled carbon nanotubes on influence of mwcnt fillers on vibroacousticCarbon nanotube (CNT) characteristics, besides the processing conditions, can change significantly the microwave absorption behavior of CNT/polymer composites.
