"Shear Banding in Entangled Polymers: Real or Artificial? "
Whether entangled polymers shear band, particularly in the steady state, is a fundamental and much pursued issue in polymer rheology. We have investigated this problem using particle tracking velocimetry for various entangled systems such as conventional polymers and DNAs. I will present our experimental results and discuss whether shear banding is an inherent property of entangled systems or could be attributed to experimental artifacts such as inhomogeneous stress field from the flow geometry.
