Abstract |
Carbon nanomaterials were used to enhance desired properties of polymeric matrices. In this work, mechanical and acoustic properties of polyurethane (PU) hybrid nanocomposites were investigated. PU nanocomposites foams containing multi-walled carbon nanotubes (MWCNT) and graphene nanoplatelets (GNPs) were used to evaluate effects of single and hybrid nanofillers by means of tensile test and acoustic transmission loss analysis. The results showed a synergistic effect between nanofillers, which the hybrid nanocomposites exhibit better mechanical and acoustic properties, relative to single inclusion of the nanofillers. The fabricated nanocomposites were also studied usingscanning electron microscopy (SEM) and X-Ray Diffraction analysis (XRD). These hybrid nanofillers improved dispersion quality in the polymer matrix, which tensile strength of PU is improved about 43% with 0.25 wt% addition of GNPs/CNTs hybrids. In addition, transmission loss of PU/GNPs+CNTs enhanced about 50%. Keywords: Polyurethane, Graphene, Carbon Nanotube, Nanocomposite. | |||||||||
