Counterion-Condensation-Induced Collapse of Highly Charged Polyelectrolytes
Abstract
Dilute or semidilute solutions of polyelectrolytes show below a critical temperature the phenomenon of counterion condensation. This effect leads (a) to a decrease of the effective total charge of the macroion and (b) to a counterion-induced attraction between different parts of the chain. In this paper we provide simple scaling arguments that allow one to calculate the chain size and the effective total charge as a function of temperature, solvent quality etc. Especially we show that effect (a) alone leads to a continuous reduction of the chain size with decreasing temperature. Due to a feedback-type mechanism effect (b) amplifies this collapse process in such a way that it is reminiscent of a first-order phase transition.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
