Abstract

In response to the Letter Wang et al. (2014) challenging the results of Li et al. (2013), the present letter addresses the specific concerns in the order that they are raised. (1) Whether the material properties (molecular weight, concentration, and polydispersity index) of the samples used in [Li et al. (2013)] agree with Table I in the same paper? (2) What is the true shear banding phase diagram, if any? (3) Are the shear cessation tests carried out by Li et al. (2013) in the regime where nonquiescent relaxation is expected? (4) How to minimize edge effects? (5) How would other factors, such as location of particle tracking velocimetry observation, plastic film on meniscus, misalignment, and surface treatment, affect the velocity profiles?
