abstract = {A priori prediction of the flow properties ofpolydisperse
rodlike macromolecules is a prerequisite for
theunderstanding of many industrial and biological
processes. Usingmixtures of two naturally monodisperse
viruses, we create abenchmark bidisperse suspension of
rodlike colloids to test theeffect of length bidispersity on
the shear flow behavior. We findthat the zero-shear
viscosity is a nonlinear function of the fractionof long
rods because of the strong length dependence of
therotational dynamics, which determine this quantity.
Withincreasing concentration and fraction of long rods, the
shearthinning gets more pronounced, following the
predictions of ourrecently proposed theory which we extended
for bidisperse mixtures. This theory allows for a
quantitative prediction of the flow properties of bi- and
polydisperse mixtures of ideal rods at least for moderate
polydispersity.},
