Abstract
The effect of non-adsorbing, flexible polymer on the isotropic-nematic
transition in dispersions of rod-like colloids is investigated. A widening of the
biphasic gap is observed, in combination with a marked polymer partitioning
between the coexisting phases. Under certain conditions, areas of isotropicisotropic-
nematic or isotropic-nematic-nematic three-phase coexistence appear in
the phase diagram of rod-polymer mixtures.
