The mean-field theory describing the conformation of an ionizable
polymer chain(weak polyacid or polybase) grafted at one end onto
an impermeable planar surface and immersed into a water-salt solution
is presented. The dependences of the brush thickness and degree of
chain ionization on grafting density and ionic strength of the solution
are analyzed. It is shown that the annealing of the brush affects
the brush structure mostly at low ionic strength of the solution
and relatively sparse grafting. The nontrivial effect of an increase
in the brush thickness with decreasing grafting density and/or increasing
ionic strength is predicted.
