Abstract
The equilibrium structure of a monolayer formed by long polyelectrolyte
chains grafted at one end onto an impermeable planar surface is analyzed.
In contrast to the case of uncharged grafted polymer layer the unit
density profile in a swollen state is not of the parabolic, but of
the exponential type. The decrease in the solvent strength below
the theta-point leads to the jump-wise collapse transition accompanied
by the drastic change in the shape of the density profile. The increase
in the ionic strength of the solution causes gradual decrease in
the layer dimensions and change of the density profile which tends
to the parabolic shape.
