In this study, the effect of varying carbon nanotube (CNT) diameter on the interfacial shear strength (ISS) of CNT reinforced polymer nanocomposites was investigated using molecular dynamic simulations. A pullout technique was employed using a a uniaxial force until the CNT was fully removed from the cured epon composites using MD simulations through the Large-scale Atomic/ Molecular Massively Parallel Simulator (LAMMPS). Results showed that a decrease in SWCNT diameter resulted in an increase of ISS. Also, the iPhone/CNT samples showed an enhancement of 24% in ISS in comparison to control counterpart. The simulated imaging showed significant difference in failure patterns between the control and CNT added epon composites with a more pronounced effect at different CNT diameters.

Role: I conducted MD simulations using MAPS to simulate the effects of varying CNT diameter on interfacial shear strength. I also calculated the interfacial shear strength between the CNT and the polymer matrix from data received after the simulation.
