An equilibrium conformation structure of a monolayer formed by polyele
ctrolyte chains grafted at one end onto an impermeable planar surface
and immersed in a solvent is analyzed on the basis of the asymptotic s
olutions of the Poisson-Boltzmann equation at arbitrary grafting and c
harge density including the regime of nonoverlapped grafted polyions.
The cases of both salf-free and salt-added solution are considered. Th
e effect of grafted polyion orientation due to long-range interactions
under the conditions of loose grafting is analyzed. The corresponding
diagrams of the states of the grafted polyelectrolyte layer in the co
-ordinates grafting density-charge density and grafting density-ionic
strength for the cases of both good solvent and THETA-solvent are pres
ented.
