Abstract Details

2015, Master of Science, University of Akron, Polymer Science.
We employ rotational shear rheometry to investigate the transient and steady-state responses of entangled polybutadiene solutions that undergo massive wall slip. Wall slip behavior is studied in both the rate-controlled and stress controlled modes. Unlike the entanglement-disentanglement transition 1, we expect a stick-slip transition (SST) to emerge in an idealized setup of simple shear. Particle tracking velocimetry (PTV) is also applied to directly capture the image of wall slip during startup shear. Comparison between the rate-controlled and stress-controlled data confirms the existence of SST in creep as well as anticipated stress plateau from startup shear.
