abstract = {Mixtures of semiflexible polymers with a mismatch in either
their persistence lengths or their contour lengths are
studied by Density Functional Theory and Molecular Dynamics
simulation. Considering lyotropic solutions under good
solvent conditions, the mole fraction and pressure is
systematically varied for several cases of bending stiffness
κ (the normalized persistence length) and chain length N.
For binary mixtures with different chain length (i.e.,
NA=16, NB=32 or 64) but the same stiffness,
isotropic-nematic phase coexistence is studied. For mixtures
with the same chain length (N=32) and large stiffness
disparity (κB/κA=4.9 to 8), both isotropic-nematic and
nematic-nematic unmixing occur. It is found that the phase
diagrams may exhibit a triple point or a nematic-nematic
critical point, and that coexisting phases differ
appreciably in their monomer densities. The properties of
the two types of chains (nematic order parameters, chain
radii, etc.) in the various phases are studied in detail,
and predictions on the (anisotropic) critical behavior near
the critical point of nematic-nematic unmixing are made},
