Abstract: S1.00019 : Densely grafted brushes of gradient copolymers: an effective Flory-Huggins parameter approach
Author:
Manufacturing of gradient copolymers becomes cheaper and easier
nowadays. There is
a wide spectrum of experimental applications for such polymers.
In this work, densely
grafted gradient copolymer (monomers distribution function $g(n)$
along the chain is
assumed to be a power law) brushes in a selective solvent are
considered. Equilibrium
thermodynamic properties of the system are investigated within
the frames of a simple
mean-field approach and an effective Flory-Huggins parameter
$\chi_{eff}(n)$
approximation. Constructed profiles for polymer concentration
demonstrate non-linear
behavior, however the brush thickness varies in direct proportion
to the molecular
weight of copolymer. Coil-Globule transition properties in such a
system are
investigated as well.
