Abstract
Composites of polyurethane (PU)/multi-walled carbon nanotubes (MWCNTs) have been successfully prepared by using Solvent Mixing approach followed by injection molding. Field emission scanning electron microscopy has been performed and indicated reasonable dispersion of MWCNTs into PU matrix. Mechanical characterization shows that tensile modulus and stiffness of PU/MWCNT composites have been greatly improved by 23 times and 15 times, respectively, for 7 wt% in comparison with pure PU. Torsion and three-point bend tests revealed that torque and flexural modulus of PU composite with 7 wt% of MWCNTs have also been improved in comparison with pure PU. Excellent load transfer property of MWCNTs and their interaction with polymer matrix due to even dispersion are the suggested reasons for the improvement in mechanical properties. This significant improvement in mechanical properties of PU/MWCNT composite opens up several new avenues of mechanical applications like fabrication of shoes, gloves, helmet and other materials for armed force personnel.
