Water and Ion Pairing in Polyelectrolyte Multilayers

Farhat, Tarek, Yassin, Ghada, Dubas, Stephan T., Schlenoff, Joseph B.·1999·Langmuir

Abstract

The water content in multilayers made from poly(styrenesulfonate) and poly(diallyldimethylammonium chloride) was determined using infrared spectroscopy and thermal gravimetric analysis. Under ambient conditions the polyelectrolyte multilayer contains 10−20 wt % water, which is removed by heating under dry conditions to 100 °C. FTIR comparison of multilayers with solution-precipitated polyelectrolyte complexes of the same polymers revealed that both the composition and sulfonate group environment were identical.

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.
