Paper Abstract

In the present study, multiwalled carbon nanotubes (MWCNTs) reinforced shape memory polymer (SMP) nanocomposites were prepared with a high shear mixing process. The shape memory effect and thermomechanical behaviors were characterized. A well dispersion of MWCNTs in SMP were reached with the current mixing process and brought in enhanced mechanical properties. The glass transition temperature of the nanocomposites does not vary with the MWCNT content. In the glass transition range, the addition of MWCNTs enhances the modulus of the SMP significantly, indicating the increased recovery force. The constrained recovery stress increased with the addition of carbon nanotubes.
